The quadratic formula is

x = (-b +- root2 (b^2 - 4ac))/(2a)

Your equation

4x^2 = 0

can be re-written into

4x^2 + 0x + 0 = 0

Substituting the coefficients into the quadratic formula, we have

x = (-b +- root2 (b^2 - 4ac))/(2a)

=> x = (-0 +- root2 (0^2 - 4(4)(0)))/(2(4))

=> x = (-0 +- root2 (0 - 0))/(8)

=> x = 0
