Question 647256: Solve by Factoring: 3x2 = -9x What are the solutions for x?

You can put this solution on YOUR website! Hi, my name is Aaron I am in 10th grade and im in honors trig/pre-calc.
Factoring is mostly about practice.
Start by setting one side equal to zero.
3x^2+9x=0
we can factor out a 3x
3x(x+3)=0
which means x equals -3 or zero.
I would really appreciate your recomendation, most touters are asleep, however I stayed up to help people who are staying up late struggling. Feel free to email me if you are having trouble still , good luck
-Aaron
