Question

When using the inspection method to rewrite the rational expression x^2-10x+14/x-8 , what constant term must the numerator have for (x-8) to be one of its factors? What number must you add to (and subtract from) the numerator's constant term to derive (x-8) as a factor? For the numerator to have (x-8) as a factor, its constant term must be_____ . To get this number, add and subtract ______ from the numerator’s constant term?

Answer 1

To have (x-8) as a factor of x^2-10x+k, we know that it should be
(x-8)(x-2) (to match -8+(-2)=-10) which expands to x^2-10x+16.
