Question 273948
Yes, you will move everything to the left and simplify = 0

x^2 + 4x - 8 = 0

Factor(reverse FOIL) 
(x    )(x    )
(x +  )(x -  ) what can we use to get -8? (4 * 2) or (8 * 1) and what will give us a total of +4x?

Neither will work 

We must use quadratic equation to find values of x
