HELPP MEDALS!!

For the polynomial f(x) = 6x3 + 17x2 – 4x – 3, one of the roots is -3. What are the other solutions for f(x)? Use mathematical reasoning to support your response.

Answer 1

As you got one root which is known to be 3 the you have one factor which is (x+3)
then using long division U could find the other quadratic factor which will be (6x2 -x-3)
which could be solved using the general formula for x which is

X = \[\frac{ -b \pm \sqrt{b ^{2} - 4ac} }{ 2a }\]
Then you got two solutions which are known to be the other roots of the equation

Answer 2

Polynomial long division.
