You can use parentheses: ( and )

√(-2 + 8x) = √(-44 + 2x)

Much clearer & simpler that ways! If by chance you don't have access to them, you can use brackets [ & ] or something similar.

(8x - 2)^(1/2) = (2x - 44)^(1/2)

Square both sides

8x - 2 = 2x - 44

8x - 2x = -44 + 2

6x = -42

x = -7

If we're permitted to use complex values, then x = -7 works.

If not, then x = -7 is extraneous and there is no solution.
