Question

Which of these are factors of this polynomial -3x^3+15x^2+3x-15 (x+5) 3x (3x-1) (x+1) (x- 5) (x-1) -3

Answer 1

Explanation:

x - 5

x + 1

x - 1

-3

My calculator does this. Factoring might also work.

-3x^2x ( x - 5) + 3(x - 5)

(-3x^2 + 3) ( x - 5)

-3(x^2 - 1) (x -5)

-3(x - 1)(x+1)(x - 5)
