## 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]

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

#### proof Formula \( a^2 – b^2 = (a+b)(a-b) \)

### 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]
