Answer:
D
Step-by-step explanation:
To solve the quadratic equation, use the inverse operation to squaring. This will undo the exponent and allows x to be isolated. The inverse operation is the square root. This is called the square root property of equality.
(x + 2)² = 1
√(x+2)² = √1
(x+2) = ±1
x = 1 -2 and x = -1 - 2
x = -1 and x = -3
The product of the roots -1 and -3 is -1*-3 = 3
