Solve for x:

4 x^2 = 2.25

Rewrite the right-hand side of the equation.

2.25 = 9/4:

4 x^2 = 9/4

Divide both sides by a constant to simplify the equation.

Divide both sides by 4:

x^2 = 9/16

Eliminate the exponent on the left-hand side.

Take the square root of both sides:

**x = 3/4 or x = -3/4**
