Question

Which of the following is a linear factor of the polynomial below?

y = x^3 + 6x^2 + 8x

A) x + 6
B) x + 8
C) x - 4
D) x + 2

Answer 1

well do you know what a linear factor is?

Answer 2

its a straight line...right?

Answer 3

yes

Answer 4

well a linear factor form is ax + b

Answer 5

so where do you put the answers at? like do you put (for instance) (x+6) in for y?

Answer 6

if x+6 is a factor, then we have x+6=0 so x=-6 is a zero of the cubic

Answer 7

do that for the rest of the points
