Question

What is the coefficient of x in the expansion of (2x−4)^2?

Answer 1

Answer:

$-16$, $10$

Step-by-step explanation:

To get the coefficients, we first need to factor the expressions

$(2x-4)^{2}$

$(2x-4)(2x-4)$

$4x^{2}-16x+16$

The coefficient of x is -16

$(x+3)(x^{2}+7x+8)$

$x^{3}+10x^{2}+29x+24$

The coefficient of x² is 10
