Question

9v^2-64=0
solve

Answer 1

not solvable, there are 2 unknowns

Answer 2

Sorry about that.

Answer 3

@Callisto come back

Answer 4

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?

Answer 5

yea thanks

Answer 6

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