Mathematical Formula

Competitive exams are fill with maths where you need mathematical formula. So, Mathematical Formulas are very important and necessary for doing maths.

Here in this page we put together all basic mathematical formula. You need these formulas in your exams. So, you need to memorize these math formula very carefully before your exam. Here we provide few basic mathematical formula which will help you to do maths in your competitive exams.

All Algebra Formula:

  • (a + b)2 = a2 + 2ab + b2
  • (a − b)2 = a2 − 2ab + b2
  • a2 + b2 = (a + b)2 − 2ab
  • a2 + b2 = (a − b)2 + 2ab
  • (a + b)3 = a3 + b3 + 3ab(a + b)
  • (a − b)3 = a3 − b3 − 3ab(a − b)
  • a3 + b3 = (a + b)3 − 3ab(a + b)
  • a3 − b3 = (a − b)3 + 3ab(a − b)
  • a2 − b2 = (a + b)(a − b)
  • a3 − b3 = (a − b)(a2 + ab + b2)
  • a3 + b3= (a + b)(a2 − ab + b2)
  • a4 – b4 = (a2 – b2)(a2 + b2) = (a + b)(a + b)(a2 + b2)
  • a4 + b4 = (a2 + b2)2 – 2a2b2 = (a2 + √2ab + b2)(a2 – √2ab + b2)
  • a5 + b5 = (a + b)(a4 – a3b + a2b2 – ab3 + b4 )
  • a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4)
  • an − bn = (a − b)(an−1 + an−2 b + an−3 b2 + ··· + bn−1n−1)
  • (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)
  • a3 + b3 + c3 – 3abc = (a + b + c)(a2 + b2 + c2 – ab – bc – ca)
  • If a + b + c = 0, then the above identity reduces to a3 + b3 + c3 = 3abc
