Question

simplify the following binomials by using the identity (2x+3)(2x-7)

Answer 1

(2x+3)(2x-7)

using identity , (x+a)(x+b) = x²+x(a+b)+ab

we have ,

=> (2x+3)[2x+(-7)] = (2x)²+2x[3+(-7)]+(3)(-7)

=> (2x+3)(2x-7) = 4x²+2x(3-7)+(-21)

=> (2x+3)(2x-7) = 4x²-8x-21


hope this helps

Answer 2

The correct answer is "4x²-8x-21".

Step-by-step explanation:

$The \ given \ binomials are:\\\\(2x+3)(2x-7)\\\\On \ applying \ multiplication,we \ get\\\\=2x(2x-7)+3(2x-7)\\\\=4x^2-14x+6x-21\\\\=4x^2-8x-21$
