Answer:

The answer for this question is : [tex](x+4)(3x+1)(3x-1)[/tex]

Step-by-step explanation:

[tex]=9x^3+36x^2-x-4\\=(x+4)(3x+1)(3x-1)[/tex]

Answer:

Your answer is (3x + 1)(3x − 1)(x + 4) or in letter terms, B on your exam!

Step-by-step explanation:

Let's solve this together!

First we use the rational roots theorem to find a root.  

The general formula for a third-degree polynomial is  f(x) = ax³ + bx² + cx + 3

And our polynomial is   ƒ(x) = 9x³ + 36x² − x − 4

Time to define our variables!: a = 9; d = -4

According to the Rational Roots Theorem, the possible rational roots are the factors of d divided by the factors of a.

Factors of d = ±1, ±2, ±4,  

Factors of a = ±1, ±3, ±9

So there are 20 possible roots ranging from x = -4 to x = 4 that we can evaluate.

First we're going to give x = -4 a shot.

f(-4) = 9(-4)³ + 36(-4)² − (-4) − 4 = 9(-64) + 36(16) + 4 - 4 = -576 + 576 =0

It worked!  x = -4 is a root, and (x+ 4) is a factor of the polynomial

After we use synthetic division we must write the complete factorization

ƒ(x) = (x + 4)(3x + 1)(3x - 1)

There! That would be your answer, young mind!
