What are the solutions to the quadratic equation 4x2 = 64? A. x = −16 and x = 16 B.x = −8 and x = 8 C.x = −4 and x = 4 D.x = −2 and x = 2

Answers

Answer:

x = ±4

Step-by-step explanation:

4x^2 = 64

Divide each by 4

4x^2 /4= 64/4

x^2 = 16

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4

Answer:

\boxed{\boxed{x=\pm 4}}

Step-by-step explanation:

4x^2 = 64

Divide both sides by 4.

(4x^2)/4 = 64/4

Simplify.

x^2 =16

Take the square root on both sides.

√(x^2 ) =\pm √(16)

Simplify.

x=\pm 4
