Could someone please help with this two step question?
5x+x(x-2)=0
What are the solutions?
What are the x-intercepts?
5x+x(x-2) = 0
5x+x^2-2x = 0
x^2+3x = 0
x*(x+3) = 0
x=0 or x+3 = 0, so the solution are x =0 and x=-3.
The x-intercepts are the points (x,y) where values of x make y= 5x+x*(x-2) equal to 0. In this case that is (0,0) and (-3,0).

You could try this:
Factor an x.
Simplify.
Apply the zero product rule: If a*b = 0, then either a = 0, or b = 0, or both, so...
or and so
The solutions are: and
The x-intercepts are: (0, 0) and (-3, 0)
