Which of the following are solutions to the equation below? Check all that apply.

9x2 - 64 = 0

8/3 and - 8/3

x = 8/3 and x = - 8/3

Step-by-step explanation:

Remember the difference of two squares method

a² - b² = (a+b) (a-b)

Given;

9x²-64=0

We notice 9 and 64 are in square form thus can be written as

(3x-8) (3x+8) ... applying the difference in squares method to simplify

Solving for x

(3x-8) (3x+8) = 0

3x-8=0

3x=8

x = 8/3

or

3x+8=0

x = - 8/3
