Kagome_gurl8 2 years ago Anyone good with Quadratic Formulas? I have a couple of questions for you. x^2+9x-4=0 -4x^2+5x-3=0

You just throw in the numbers. For an equation ax^2 + bx + c = 0, $$x = \frac{-b \pm \sqrt{b^2-4ac}} {2a}$$

I really don't understand.

@Kagome_gurl8 Which part of it confuses you?
