Which of the following are solutions to the equation below? Check all that apply. 9x^2-64=0

A. 8

B. - 8

C. - 3/8

D. 3/8

E. - 8/3

F. 8/3

E. - 8/3

F. 8/3

Step-by-step explanation:

9x^2-64=0

Add 64 to each side

9x^2-64+64 = 0+64

9x^2 = 64

Divide each side by 9

9x^2/9 = 64/9

x^2 = 64/9

Take the square root of each side

sqrt (x^2) = ±sqrt (64/9)

We know that sqrt (a/b) = sqrt (a) / sqrt (b)

x = ±sqrt (64) / sqrt (9)

x = ± 8/3
