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

Try: http://www.mathsisfun.com/quadratic-equation-solver.html or http://www.math.com/students/calculators/source/quadratic.htm (These sites solve the equations once you put the values in.)

When you put in the values, x^2 needs the value of 1 (as there is one x^2), or it won't solve.
