  16. (x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
  17. x3 + y3= (x + y) (x2 – xy + y2)
  18. x3 – y3 = (x – y) (x2 + xy + y2)
  19. x2 + y2 + z2 -xy – yz – zx = ½ [(x-y)2 + (y-z)2 + (z-x)2]

Maths class 10 Quadratic Equation Formula

X=( -b +-(D)^.5)/2a (where D= b*b – 4ac) Hence x= (-b+- (b*b- 4ac)^.5)/2a

  • Sum of the roots = -b/a & Product of roots= c/a
  • If roots of an equation are given, then :

Quadratic equation : x*x – (Sum of roots).x + (product of the roots) =0

If Discriminant > 0, then the roots are Real & unequal or unique, lines are intersecting.

Discriminant = 0, then the roots are real & equal , lines are coincident.

Discriminant < 0 , then the roots are imaginary (not real), parallel lines.

Maths formulas for class 10 of Linear Equation Formulas

Linear Equation in one Variable is given by : ax + b=0 (Where a ≠ 0 and a & b are real numbers)

The pair of linear equations in two variables are given as : a1x+b1+c1=0 and a2x+b2+c2=0 (Where a1, b1, c1, & a2, b2, c2 are real numbers & a12+b12 ≠ 0 & a2+ b22 ≠ 0)

Then nature of roots/zeroes/solutions :

i.  If a1/a2 is not equal to b1/b2 then, system has unique solution, is consistent OR graph is two intersecting lines

ii.  If a1/a2 = b1/b2 is not equal to c1/c2 , then system has no solution, is inconsistent OR graph is parallel lines.

iii.  If a1/a2=b1/b2=c1/c2, then system has infinite solution, is consistent OR graph are coincident lines.

Maths Class 10 Arithmetic Progression (AP) Formulas

An arithmetic progression is a sequence of numbers such that the difference d between each consecutive term is constant. The sequence is represented as : a, a + d, a + 2d, a + 3d, a + 4d…… a + nd. Here a is the first term whereas (a+nd) is the (n-1)th term.

Formula for calculating the nth term = a + (n-1) d

Formula for calculating the sum of n terms = Sn = n/2 [2a + (n-1) d] 


                                                                        Sn = n/2 [a + l]

NOTE : Here a is the first term, d is the common difference, l is the last term and n is the number of terms.

Maths Class 10 Important Trigonometric Formulas


The values of the trigonometric functions are as per the trigonometric table provided beneath.


Remember these formulas : 


  1. sin (90° – θ) = cos θ
  2. cos (90° – θ) = sin θ
  3. tan (90° – θ) = cot θ
  4. cot (90° – θ) = tan θ
  5. sec (90° – θ) = cosecθ
  6. cosec (90° – θ) = secθ
  7. sin2θ + cos2 θ = 1
  8. secθ = 1 + tan2θ for 0° ≤ θ < 90°
  9. Cosecθ = 1 + cot2 θ for 0° ≤ θ ≤ 90°

Class 10th Important Circle Formulas

Formulas for a circle of radius r is given below:

  • Circumference of the circle (also the perimeter) = 2 π r
  •  Area of the circle = π r2
  •  Area of the sector of angle θ = (θ/360) × π r2
  •  Length of an arc of a sector of angle θ = (θ/360) × 2 π r
  • Area of ring = π (R× R- r× r)
  • Distance moved by a wheel in one revolution = Circumference of the wheel.
  • Number of revolutions=Total distance moved/Circumference of the wheel.


Maths Class 10 Surface Areas and Volume Formulas

For solving any mensuration question quickly one must remember these formulas by heart. In the table given below we have presented all formulas used for various shapes such as cube, cuboid, cylinder, sphere etc.

NOTE : LSA means Lateral Surface Area and TSA means Total surface Area.

Cube with a = sides of a cube) 4a2 6a2 a3
Cuboid with l = length,
b = breadth,
h = height
2h(l + b) 2(lb + bh + hl) lbh

Important Statistics Formulas

(I) The Mean of Grouped Data can be found by 3 methods.

  1. Direct Method formula: This method can be very calculation intensive if the values of f and x are large.We have big calculations and chance of making mistake is quite high.

2. Assumed mean method formula: Where a= Assumed mean and d= xi –a
This method is quite useful when the values of f and x are large. It makes the calculation easiar.In this method we take some assumed mean and calculate the deviation from it and then calculate mean using below given formula.


3. Step deviation Method Formula: Where a= Assumed mean and u  => (xi –a)/h
This method is quite useful when the values of f and x are large. It makes the calculation further easiar by dividing the deviation from common factor.


(II) The Mode of Grouped Data: The class interval having highest frequency is called the modal class and Mode is obtained using the modal class. Mode formula is given as

NOTE : Where
l = lower limit of the modal class,
h = size of the class interval (assuming all class sizes to be equal),
f1 = frequency of the modal class,
f0 = frequency of the class preceding the modal class,
f2 = frequency of the class succeeding the modal class.

(III) The median for a grouped data: The formula for finding a median of a given data is


l = lower limit of median class,
n = number of observations,
cf = cumulative frequency of class preceding the median class,
f = frequency of median class,
h = class size (assuming class size to be equal)

These were all the formulas that are quite necessary to remember and are important maths formulas for class 10. Don’t just start mugging these formulas but rather understand there concepts and it will become easier then. We have tried our best to narrow down the important formulas of class 10th.

In this article maths formulas for class 10 is described in detail.
