Question

How do I solve √ 5x-6=√ 3x+4?
I know to first square both sides and that leaves me with 5x-6=3x+4 and I have 4 possible answers which are:
x=−1
x=−0.25
x=1.25
x=5

Answer 1

Add six to both sides, and subtract 3x from both sides first.

Answer 2

x=5

Answer 3

Thanks so much!

Answer 4

Just to make sure put x = 5 in the original equation and see if LHS equals RHS.

Answer 5

Yes I know how to check it but I get confused with the order of operations. Thanks!
