Solve the quadratic equation graphically using at least two different approaches. when necessary, give your solutions to the nearest hundredth. 2x^2-3=2x

For graphic solution see attached figure.
====================================
It can be solved also by genral equation which is :
x = (-b/2a)√(b² - 4ac)
for the given equation:
2x² - 3 = 2x
∴ 2x² - 2x - 3 = 0
a = 2 , b = -2  and   c = -3
Substitute in the general equation;
∴ x = -0.823   OR   x = 1.823
