Find the roots of the polynomial equation. -x^4-4x^2-3x-12=0

Answer 1

Hello,

Let's dig into this problem.

x^4 - 4x^2 -3x - 12 = 0

Let's look at the first two terms, and the last two terms separately,

x^4 - 4x^2 and -3x-12

plus x^2 out

x2(x^2 - 4) then break down x^2 - 4 into (x-2)(x+2)

pull 3 out

-3 (x+4)

Given all this, can you find your roots! don't forget 0.
