Answer:

x = 12.633, -0.633

Step-by-step explanation:

<u>x^2 -12x + 36</u> = 44

the underlined part is (x - 6) ^2

(x - 6)^2 = 44

(x - 6) = ± $\sqrt{44}$ (both positive and negative)

(x - 6 ) = + 6.6332495807108

x = 12.6332495807108 = 12.633

(x - 6 ) = - 6.6332495807108

x = - 6.6332495807108 + 6

= -0.6332495807108 = -0.633

Solve the following quadratic equation by the square root property of equality. (x - 8)^2 = 48

NeX [460]

Solve for x over the real numbers by completing the square.

(x - 8)² = 48

Take the square root of both sides:

x - 8 = 4 √(3) or x - 8 = -4 √(3)

Add 8 to both sides:

x = 8 + 4 √(3) or x - 8 = -4 √(3)

Add 8 to both sides:

Answer: x = 8 + 4 √(3) or x = 8 - 4 √(3)
