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

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

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

3. Fox375

tha is what i was thinking too

4. mathstudent55

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

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