Question

(a+b)×(a-b) =
Answer the question ​

Answer 1

solution ⤵️

(a+b)(a-b)

in this sum we use a formula and proved it

(a+b)(a-b)

=a²-b²(identity)

proof:-(a+b)(a-b)

in multiplication of two bionomial we always get two or three terms

by cutting or grouping

(a+b)(a-b)

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

=a²-ab+ab-b2

=a²-b²

in this multiplication we cut -ab and +ab

bionomial is a type of algebraic expression which has two terms

Answer 2

Answer:

a+b)×(a-b) = a square - b square
