Question

what is 2x^2-9x+9=0 using the quadratic formula?

Answer 1

Hmm compare your quadratic equation to the standard equation \(ax^2 + bx + c=0\), and find out 'a', 'b' and 'c' for your particular equation.

Now the quadratic formula is:
\[\large x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]

Substitute obtained values of 'a', 'b' and 'c', calculate and enjoy!
