# Proof A Square Minus B Square Formula

## Proof A Square Minus B Square Formula

Are you looking for A Square Minus B Square formula? You can check the formulas of $$a^2 – b^2$$ in three ways. We are going to share the $$a^2 – b^2$$ algebra formulas for you as well as how to create $$a^2 – b^2$$ and proof.

$$=> a^2 – b^2$$ we need to add ab

$$=> a^2 – b^2 + ab -ab$$ [when you add ab then also minus ab for equal]

$$=> a^2 + ab – b^2 – ab$$ [take comman value]

$$=> a(a+b) – b(b+a)$$ [ agian take comman value]

$$=> (a+b)(a-b)$$

### verify $$a^2 – b^2$$ formula

Need to verify $$a^2 – b^2$$ formula is right or wrong. put the value of a = 5 and b=3

put the value of a and b in the LHS

$$=> a^2 – b^2 = 5^2 – 3^2$$

$$=> a^2 – b^2 = 25 – 9$$

$$=> a^2 – b^2 = 16$$

put the value of a and b in the RHS

$$=> (a+b)(a-b)$$

$$=> (5+3)(5-3)$$

$$=> (8)(2) = 16$$

Therefore $$LHS =RHS$$ [LHS = Left hand side, RHS = Right hand side]
