What can be figured out about the two x-intercepts of the equation 0 = (x - m) (x + n) just by looking at the factors?

Question

A. Both x-intercepts will be positive

B. Both x-intercepts will be negative

C. The m-factors x- intercept will be positive while the n -factors x-intercept will be negative

D. The m-factors x-intercept will be negative while the n-factors x-intercept will be positive

Answer 1

C) the signs of the x intercepts will be opposite the sign of the constant in the factors. x intercepts are x=+m and x=-n when the factors are (x-m)(x+n)
