Question 1014422
Given F(x)=x^2+2x-8 , Solve F(x) Using each method below: Show work please. 
1). Solve by graphing.
{{{graph(400,400,-10,10,-10,10,x^2+2x-8)}}}
-------------------------------------------- 
2). Solve by factoring.
(x+4)(x-2) = 0
x = -4 or x = 2
----------------------------------------------- 
3). Solve by the quadratic formula 
x = [-2 +- sqrt(2^2-4*1*-8)]/2
x = [-2 +- sqrt(36)]/2
x = [-2+-6]/2
x = -4 or x = 2
--------------------------------
