Going off that this is a quadratic I will take the following steps:

Step-by-step explanation:

$3x^2+7x=-3\\3x^2+7x+3=0$

Then I try to factor this:

I will use the discriminant which tells if the roots are real are not:

$-b^2-4ac\\(7)^2-4(3)(3)=13\\$

Since the discriminant is positive one can be sure that roots are real, and one can use the quadratic formula to get the roots. You only said describe the roots which means real or complex. Not give you the roots.

Step-by-step explanation:

$3\frac{1}{4} +2\frac{5}{6} = \frac{39}{12}+\frac{34}{12}$

$\frac{39}{12}+\frac{34}{12} = \frac{73}{12}$

$\frac{73}{12}=6\frac{1}{12}$

good luck, i hope this helps :)
