    Back :) 9v^2-64=0 Add 64 to both sides 9v^2-64+64=0+64 9v^2=64 Divide both sides by 9 9v^2 /9=64 /9 v^2 = 64/9 Take square root on both sides sqrt(v^2) = ±sqrt(64/9) v = 8/3 or v= -8/3 Do you understand this?

    welcome, if you don't mind, can you try x^2 = 9/4, just want to make sure you understand.
