Question

a² – b² is equal to *​

Answer 1

Answer:

(a+b)(a-b)

hope it helps you ☺️

Answer 2

a² - b² = (a+b)(a-b)

Here a and b are the real numbers.

(a+b)(a-b)

=a(a-b)+b(a-b) [Addition Distributive Law]

=a²-ab+ba-b² [Addition Distributive Law]

=a²-ab+ab-b² [Multiplication Commutative Law]

=a²+0-b² [Addition Law of Identity]

=a²-b² [Addition Law of Identity]

so, a² - b² = (a+b)(a-b)

Addition Distributive Law: (A + B) X = (A X) + (B X)

Multiplication Commutative Law: XY=YX

Addition Law of Identity: A+(-A)=0 and A+0=A

Hope this helps!!
