A B 3 Formula In Maths

A b c 2 a 2 b 2 c 2 2ab 2bc 2ca.

A b 3 formula in maths. A b 3 a 3 3a 2b 3ab 2 b 3. Given a general quadratic equation of the form ax bx c 0 with x representing an unknown a b and c representing constants with a 0 the quadratic formula is. Mathematical formulae algebra 1. Since a b 3 a b a b a b you expand one pair first and then the last a b.

Basically a 3 b 3 has many formulae which are also called as identities. A 3 b 3 a b a 2 ab b 2 a 3 b 3 a b a 2 ab b 2 a b 3 a 3 3a 2 b 3ab 2 b 3. Where the plus minus symbol indicates that the quadratic equation has two solutions. It s quite easy actually to find this if you know basic algebraic expansion.

A b 3 a 3 b 3 3ab a b a b 3 a 3 b 3 3ab a b a 3 b 3 a b a 2 b 2 ab a 3 b 3 a b a 2 b 2 ab a b c 3 a 3 b 3 c 3 3 a b b c c a a 3 b 3 c 3 3abc a b c a 2 b 2 c 2 ab bc ac if a b c 0. Firstly let me explain one derivation a b a b a b a b 3.
