What is a simple mathematical formula?
Basic algebra formula
a2 – b2 = (a – b)(a + b) (a + b)2 = a2 + 2ab + b2. a2+ b2 = (a + b)2 – 2ab. (a – b)2 = a2 – 2ab + b2. (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.

What are the 10 formulas?
Class 10 Maths Formulas for Algebra And Quadratic Equations
- (a+b)2 = a2 + b2 + 2ab.
- (a-b)2 = a2 + b2 – 2ab.
- (a+b) (a-b) = a2 – b.
- (x + a)(x + b) = x2 + (a + b)x + ab.
- (x + a)(x – b) = x2 + (a – b)x – ab.
- (a + b)3 = a3 + b3 + 3ab(a + b)
- (a – b)3 = a3 – b3 – 3ab(a – b)
- (x – a)(x + b) = x2 + (b – a)x – ab.
