Question

(4a+3b)^2 - (4a-3b)^2 +48ab

Answer 1

Hey user here is your answer.......

----->(4a+3b)^2-(4a-3b)^2+48

◆Using identity
(a+b)^2=a^2+b^2+2ab

◆(a-b=^2=a^2-2ab+b^2

So,

◆(4a)^2+(3b)^2+2(4a)(3b)-(4a)^2-2(4a)(3b)+(3b)^2+48ab

◆16a^2+9b^2+24ab-16a^2+24ab-9b^2+48ab

◆24ab+24ab+48ab


◆96ab

Thanks☺️
