Completely simplify spare root of 24x^6

(x−8)(x+3)(2)

=2x2−10x−48

Step-by-step explanation:

If we count roots according to their multiplicity (see The Factor Theorem), then: A polynomial of degree n can have only an even number fewer than n real roots. Thus, when we count multiplicity, a cubic polynomial can have only three roots or one root; a quadratic polynomial can have only two roots or zero roots.
