Answer 1

Answer:

4a^2 – 9b^2

Step-by-step explanation:

(2a-3b) (2a + 3b)

= (2a)^2 - (3b)^2...(a+b)(a-b) = a^2 – b^2

= 4a^2 – 9b^2

hope that helps u :)

Answer 2

The given polynomials are 2a+3b and 2a−3b we multiply them as follows:

(2a+3b)(2a−3b)=(2a×2a)+(2a×−3b)+(3b×2a)+(3b×−3b)=4a

2

−6ab+6ab−9b

2

=4a

2

−9b

Hence, (2a+3b)(2a−3b)=4a
