Could someone help me with this equation?
Use the quadratic formula to solve the equation...
2x^2 - x = -10

    Do you know the quadratic formula?

    x = [-b (+ or -) [sqroot](b^2 -2ac)] / [2a]

    With your equation, think ax^2 + bx + c = 0

    If you add 10 to both sides, you now have:

    2x^2 - x + 10 = 0

    Using ax^2 + bx + c = 0, we know that a=2, b=-1, and c=10

    Plug those into your equation!

    * By equation, I meant quadratic formula. Sorry for being vague.

    ** As well, I typed the quadratic formula wrong.

    It's:
    x = [-b (+ or -) [sqroot](b^2 -4ac)] / [2a]

    Thank you!
