Question

Helpppp Plsssss!!! Thanks

Answer 1

Answer:

B. $-5x(x^{2} +2x+3)$

Step-by-step explanation:

$-5x^{3} -10x^{2} -15x$

Apply exponent rule

$-5x^{2} x-10xx-15x$

Rewrite 15 as 5*3

Rewrite 10 as 5*2

=$5x^{2} x-5*2xx-5*3x$

Factor out common term -5x

=$-5x(x^{2} +2x+3)$

Answer 2

Answer:

It's B

Step-by-step explanation:

-5x(x^2)=-5x^3

-5x(2x)= -10x^2

-5x(3)= -15x^2

All together: -5x^3 - 10x^2 - 15x
