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 \( LHS = RHS \)
Proof Formula of \((a+b)(a-b) = a^2 – b^2 \)
Summary (a+b)(a-b)
