Answer:

[tex]-16[/tex], [tex]10[/tex]

Step-by-step explanation:

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

[tex](2x-4)^{2}[/tex]

[tex](2x-4)(2x-4)[/tex]

[tex]4x^{2}-16x+16[/tex]

The coefficient of x is -16

[tex](x+3)(x^{2}+7x+8)[/tex]

[tex]x^{3}+10x^{2}+29x+24[/tex]

The coefficient of x² is 10

plz mark me brainliest. :)
