How do you determine if (x - 1) is a factor of f(x) = x^3 + 4x^2 + x - 6?

Back

Evaluate f(1). If f(1) = 0, then (x - 1) is a factor.

If f(x) = x^3 + 4x^2 + x - 6, what is f(1)?

Back

f(1) = 1^3 + 4(1^2) + 1 - 6 = 0, so (x - 1) is a factor.

If f(x) = x^3 + 4x^2 + x - 6, what is f(2)?

Back

f(2) = 2^3 + 4(2^2) + 2 - 6 = 20, so (x - 2) is not a factor.
