3.5

Explanation:

square means 1/2.so,1/2(2x-3)=(2)^2

then square cancel by square. 2x-3=4

2x=4+3, 2x=7then divided by 2.

x=3,5

Answer:

First, we have to add 3 to both sides.

√(2x) - 3 + 3 = 2 + 3

Then we simplify the equation,

√(2x) = 5

Divide both sides of the equation by
√(2)

(√(2x) )/(√(2)) = (5)/(√(2))

Finally, simplify.

x = (5√(2))/(2)

Therefore, our answer is
x = (5√(2))/(2)
