Question

-4x^2=-11x+9 solve using the quadratic formula

Answer 1

Do you know what the quadratic formula is?

Answer 2

No

Answer 3

This is the quadratic equation:\[\frac{ -(b) \pm \sqrt{(b)^2 -4(a)(c)} }{ 2(a) }\]
where the letters "a", "b", and "c" are found from your equation. We have to first put it into a form that we are able to use the quadratic equation.

So move the equation all to one side, either the left or right side and have the other side equal to zero. Can you do that for me?

Answer 4

your equation in standard form to use the quadratic equation should look similar in this form:
\[ax^2 + bx +c\]the signs may be different and the numbers but it should be similar in format.
