Hello students, in today’s post, I will give you some formulas of maths which are useful for you. So if you want to study online, you can read with the help of our website, but in this post, I will give you pdf and text. i give you maths formulas

Algebraic Formulas (MATHS)

So students, first of all I give you algebraic formulas of maths

Important Algebraic Formula

  • (a+b)² = a² + b²+2ab
  • (a – b)²= a²+b² – 2ab
  • a²-b² = (a + b) (a – b)
  • a²+ b² = (a+b)² – 2ab or
  • a²+b² = (a – b)²+2ab
  • a3+ b³ = (a + b)(a² – ab+b²) = (a+b)3 – 3ab(a+b)
  • a3-b3= (a – b)(a²+ab+b²) = (a – b)3 + 3ab(a – b)
  • 2(a²+b²) = (a+b)² + (a – b)²
  • (a+b)² – (a – b)² = 4ab
  • a+b+= (a + b) (a – b)[(a+b)2-2ab]
  • (a – b)² = (a+b)² – 4ab
  • (a+b)²= (a – b)² + 4ab
  • a+b= [(a+b)2-2ab]2-2(ab)2
  • (a+b+c)² = a²+b² + c²+2ab+2bc + 2ca
  • (a+b-c)²= a+b²+c²+2ab-2bc-2ca
  • (a-b-c)²= a²+b2+ c² – 2ab+ 2bc-2ca
  • a3+b3+c3-3abc = (a+b+c) (a²+b²+c²-ab-bc-ca)
  • a++ a²b²+b+= (a²+ab+b²)(a² – ab+b²
  • a+1)(a² – a + 1)
  • a² + a² + 1 = (a²+a+
  • if a+b+c=0 then a3+b3+c3 = 3abc
  • a8-b8 = (a+b)(a² + b²)(a+b)(a – b)
