A -1 or -9
Explaination
Factor the quadratic equation: $1987_w132_h18.png$
$9217_w142_h18.png$
For this expression to be true, the left side of the expression must equal zero. Therefore, either (x + 1) or (x + 9) must equal zero:
If (x + 1) = 0, x must equal -1
If (x + 9) = 0, x must equal -9
So the solution is that x = -1 or -9.
B 2 or 1
C 8 or 3
D 7 or -2
