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 don't have to use quad formula to figure these out. You can complete the square. But if you want to use quadratic formula, here it is:

\[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

Answer 2

Answer 3

to use the formula you should match your equation to
a x^2 +b x + c=0

can you find a, b and c for the first equation?
