## Fox375 Group Title Solve x2 + 9x + 9 = 0 one year ago one year ago

1. Natalieee Group Title

Is that suppose to be 2x+9x+9=0 ?

2. mathstudent55 Group Title

I think teh first term is: x^2 If the left side can't be factored, then use the quadratic formula.

3. Fox375 Group Title

tha is what i was thinking too

4. mathstudent55 Group Title

Have you tried solving yet? Can the left side be factored?

5. satellite73 Group Title

you will not be able to factor you need to use the quadratic formula $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$ with $a=1,b=9,c=9$
