16x^2 - 64 = 0

16x^2 = 64

x^2 = 64/16

x^2 = 4

sqrt{x^2} = sqrt{4}

Answer:

B and F

2, -2

Step-by-step explanation:

[tex]16x^{2} -64=0[/tex]

Add 64 to both sides.

[tex]16x^{2} -64+64=0+64[/tex]

Simplify

[tex]16x^{2} =64[/tex]

Divide both sides by 16.

[tex]\frac{16x^{2} }{16} =\frac{64}{16}[/tex]

Simplify

[tex]x^{2} =4[/tex]

[tex]x=\sqrt{4} ,-\sqrt{4}[/tex]

Simplify

[tex]x=2,-2[/tex]
