Question

Anyone good with Quadratic Formulas? I have a couple of questions for you.

x^2+9x-4=0

-4x^2+5x-3=0

Answer 1

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

Answer 2

I really don't understand.

Answer 3

@Kagome_gurl8 Which part of it confuses you?
