This is the quadratic formula, you will use this to find roots.
Here is a basic problem on how to solve the quadratic formula.
The roots are x=-7xsquared+4x-2 so then -7=a 4=b -2=c. Then you would plug it in to the quadratic formula. Then it should look like this -4 plus or minus the square root of 4squared-4(-7)(-2)
------------------------
2(-7)
Then you simplify -4plus or minus the square root 16-56
x= ----------------------------------------------------
-14
So your answer would be -4 plus or minus the square root of -40
