Solve the quadratic equation for x. what is the product when the roots are multiplied? (x + 2)2 = 1 a) −3 b) −6 c) −9 d) 3

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

answer: what are the following choices
