Quadratic Equations Made Easy: Solve 2x^2+3x-9=0 by Completing the Square!

[@davidpatterson5426]

Easily factored instead of completing the square: (2x - 3)(x + 3) = 0, so x = 3/2 & -3.

where is 4 coming from

[@CalvinceOnlineMath]

Which 4 are you referring to please?

[@farjanajahan3222]

It. Can. Do. Medilturm. Fraction. For. X.

[@brett54]

Why divide by 2? Instead I multiplied it first by 2, then by 4 (so times 8 overall) thus avoiding fractions in my working until the last step.

Completing the square method requires that you make the coefficient of x squared be 1
