Answer:

Find an answer to your question The polynomial p(x) has factors of x – 5 and x + 8. Which MUST be correct?

Step-by-step explanation:

If x – a is indeed a factor of p(x), then the remainder after division by x – a will be ... the polynomial (courtesy of the Remainder Theorem), but x – a is also a factor ... completed division: 2 2 5 0 7 ... x + 4 is a factor of 5x4 + 16x3 – 15x2 + 8x + 16.

Arlecino [84]

Answer:

All real numbers

Step-by-step explanation:

-3(10x - 4) = 5(-6x + 1) + 7

-30x + 12 = -30x + 5 + 7

-30x + 12 = -30x + 12

-30x = -30x

0 = 0

If x = -7, evaluate the following expression:<br><br> (x − 2)(x+14)<br> ——————-<br> x(x + 8)

Answer:

Step-by-step explanation:

$\text{Given that}~ x = -7\\\\\dfrac{(x-2)(x+14)}{x(x+8)}\\\\\\=\dfrac{(-7-2)(-7+14)}{-7(-7+8)}\\\\\\=\dfrac{(-9)(7)}{-7(1)}\\\\\\=\dfrac{-63}{-7}\\\\\\=9$
