Question

Is (x-7) a factor of (x2-5x+14)?
Yes or no

Answer 1

Explanation:

Is the given equation factorable?

(x - 7)(x - 2) = x^ - 9x + 14 That doesn't work.

-7 * - 2 = 14 but the middle term is - 9 not - 5

x - 7 is not a factor of x^ - 5x + 14

What is?

Something very ugly (x - 2.5 +/- 2.783 i )
