I need some help solving for x...

Question

It says to slove
7x+x(x-1)=0
It also asks for the x intercept

Answer 1

7x+x2 -x=0
6x + x2 = 0
x (6+x)=0

dividing x on both side.
x (6+x)/x=0/x
6+x= 0
x= -6

:)

Answer 2

From
x (6+x)=0
we get x=0, or (6+x)=0, therefore
x=0, or x=-6
These are the x-intercepts.

Answer 3

Thank you both for your help!!!
