Use synthetic division to divide.
-$$\frac { x ^ { 2 } + 5 x - 84 } { x - 7 }$$
A) $x + 12 - \frac { 168 } { x - 7 }$
B) $x - 12$
C) $x - 12 - \frac { 168 } { x - 7 }$
D) $x + 12$

Question

Quizplus · Accepted Answer

Using synthetic division with $x - 7$, we set up the division with 7 as the divisor and the coefficients of $x^2 + 5x - 84$ as the dividend: 1 (for $x^2$), 5 (for $5x$), and -84. The process yields a quotient of $x + 12$, making option D correct.
