Question

simplify (a+b)(a-b)=a^2-b^2​

Answer 1

$\huge\blue{Solution}$

(a+b)(a-b)

a(a-b)+b(a-b)

${a}^{2} - ab + ab - {b}^{2}$

$= {a}^{2} - {b}^{2}$

Answer 2

Answer:

Step-by-step explanation:

Expand  

( a − b ) ( a 2 + a b + b 2 )

by multiplying each term in the first expression by each term in the second expression.

a 2 + a (a b ) + a b 2 + ( − b a 2 − b ( a b )b−  b 2 )
