I think the answer is no because the remainder is -460, but I'm not sure...

this is it factored −2(x3−7x2−12x−10)

Okay thanks, but idk if that's what it's asking.
I substituted x with -5 to get -460, and it should be 0 if x = -5 was the answer right?

tbh I'm not really sure I don't wanna give you the wrong answer sry I just know that's its factored and this is it simplified −2(x^3−7x^2−12x−10)
