Question 155386: I am struggling with Algebra and quadratic equations. I do not understand how to solve the following:
solve: 3x + x(x-2)= 0
find the x-incercepts of f(x)=3x + x(x-2).
The answer is 0, -1 as shown in my text but I do not undertand how to arrive at the intercepts, I get 3x + x^2 -2x = x^2 -x =0? This does not look like a quadratic formula.: I am struggling with Algebra and quadratic equations. I do not understand how to solve the following:

You can put this solution on YOUR website!Solve for x:
 Simplify the left side by factoring an x.
 Simplify.
 Apply the zero product rule: If a*b = 0, the either a =0, or b = 0, or both.
 or  so
