Question

5x^3 + x^2 - 20x - 4

Answer 1

factorize or solve = 0?

Answer 2

factor

Answer 3

ok, with x^3 u usually have to guess one of the solutions
and then make polinomial division

Answer 4

but thre might be another way for this one let me check 1 sec

Answer 5

(x-2)(5x^2+11x+2)

Answer 6

(x-2)(5x^2+11x+2)

Answer 7

(x-2) (x+2) (5 x+1)

Answer 8

yes, is a double fact first asociate 5x³+x² and - (20x-4)
so x²(5x+1)-4(5x+1)

Answer 9

\[5x^3+x^2-20x-4=(5x^3+x^2)+(-20x-4) \]
\[=x^2(5x+1)-4(5x+1)=(5x+1)(x^2-4)=(5x+1)(x-2)(x+2)\]
