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!
