Question 199794: I am trying to come up with a quadratic equation that will have 2 solutions:
0 & -2.
I'm a first year student, who has been out of school for 30 years, and I'm having a hard time with this. This is a bonus question for my next test, and I need all the help I can get! Can you please help me?
Thank you

You can put this solution on YOUR website!
x=0 or x=-2 Start with the given solutions


x=0 or x%2B2=0 Get all the non-zero values to the left side


x%28x%2B2%29=0 Combine the two equations (using the zero product property)


x%5E2%2B2x=0 Distribute


So the quadratic equation is y=x%5E2%2B2x
