I really need this help , if you help me I will give you a MEDAL and a Great Fan Testimonial! :)

Answer 1

:(

Answer 2

I figured it out!

Answer 3

Okay first you can start by finding the multiples of 180.

Which is quite a bit. So I'll give you the first two that can help with synthetic division.

Answer 4

-4 and 3 are zeroes.

Answer 5

So you're left with (x+4)(x-3)(3x^2-4x-15)

Answer 6

Then, you factor that polynomial which is (x-3)(3x+5)

Answer 7

So you're solution is 2(x-3)^2(x+4)(3x+5)
