## a Plus b into a minus b (a+b)(a-b)

Are you looking for (a+b)(a-b)? You can check the formulas of (a+b)(a-b) in three ways. We are going to share the (a+b)(a-b) algebra formulas for you as well as how to create (a+b)(a-b) and proof.

we can write:$$(a+b)(a-b) = a \times (a-b) + b \times (a-b)$$

start multiplication $$(a+b)(a-b) = a^2 – ab + ab – b^2$$

calcualte $$(a+b)(a-b) = a^2 – b^2$$ [ab – ab =0]

Formula of $$(a+b)(a-b) = a^2 – b^2$$

### (a+b)(a-b) Verifications

Need to verify (a+b)(a-b) formula is right or wrong. put the value of a = 5 and b=3

put the value of a and b in the LHS

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

$$=> (a+b)(a-b) = 8 \times 2$$

$$=> (a+b)(a-b) = 16$$

put the value of a and b in the RHS

$$=> a^2 – b^2$$

Put the Value $$=> 5^2 – 3^2$$

Square of the $$=> 25 – 9$$

Simplify Calculation $$=> 16$$

Threfore $$LHS = RHS$$
