Question

I need Algebra Help Please

Answer 1

`x^2-2x+4-(15)/(x+2)`

Explanation:

Synthetic division is a useful tool for problems of this sort. (see below)

Another way to work this one is to make use of the remainder theorem. The remainder from division by x+2 will be the value of the function at x=-2 (the value of x that makes the divisor be zero).

(-2)³ -7 = -8 -7 = -15

Only one answer choice shows a remainder of -15, and all agree on the quotient.

`x^2-2x+4-(15)/(x+2)`
