Question 329084: A.) Solve 6x+x(x-2)=0
What are the solutions?
B.) find the x-intercepts of f(x)=6x+x(x-2)
What are teh x-intercepts?

6x+x(x-2)=0
6X+X^2-2X=0
X^2+4X=0
X(X+4)=0
X=0 ANS.
X+4=0
X=-4 ANS.
-------------------
f(x)=6x+x(x-2)
F(X)=6X+X^2-2X
F(X)=X^2+4X
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, x^2 +4x).
X intercepts=(-4,0) & (0,0) ans.
