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]
