Question

One root of f(x) = 2x3 + 9x2 + 7x – 6 is –3. Explain how to find the factors of the polynomial.

Answer 1

\[2x^3+9x^2+7x-6\]
is our equation. Now since a root is -3, we can factor out x-3 from the equation.
First factor out x-3 from the equation at the top and then see if that helps

Answer 2

a lil bit

Answer 3

yes, first factor out x-3, and then tell me what you got. Then we can continue the problem

Answer 4

what about the second part

Answer 5

we'll get there

Answer 6

The first step is to factor out x+3

Answer 7

ATTENTION I MESSED UP EARLIER FACTOR OUT X+3 NOT X-3

Answer 8

Sorry about that. Because -3 is a root, x + 3 would be needed to factor out because -3 + 3 = 0

Answer 9

ok

Answer 10

ur prolly gonna use polynomial long division

Answer 11

r u stuck? If you are feel free to ask away.

Answer 12

nah i got it actually

Answer 13

Okay, the whole thing?
