B)16x2 - 9y2

C)16x2 + 24xy + 9y2

D) 16x2 + 9y2

Answer 1

Alrighty! :D

Do you know any algebraic property like this?

\[a^2 - b^2 = (a+b)(a-b)\]

? :D

Answer 2

Yes.

Answer 11

(4x+3y)(4x-3y)=(4x)^2+4x*3y-3y*4x-(3y)^2=16x^2-9y^2

Answer 12

yes you may, @E.ali

Answer 13

Thank u Modom !:)
Look :
(a+b)^2=a^2+2ab+b^2
(a-b)^2=a^2-2ab+b^2
a^2-b^2=(a+b)(a-b)
(x+a)(x+b)=x^2+(a+b)x+ab
and ...
They re very important .
I think u can proof them for your self :)
