Question

Without actually multiplying, decide which of the following polynomials could be the product of (x−2)(x+3)(x-5). Justify your choice.

A: x^3-4x^2-11x-5
B: 2x^3-4x^2-11x+30
C: x^3-4x^2-11x+30
D: 2x^3-4x^2-11x-5​

Answer 1

C

Explanation:

no coefficients in front of the x therefore there cannot be any coefficients in front of the x^3 term

(-2)(3)(-5) = 30 therefore must be +30 at the end.

only answer left is C
