Answer:
C. x=-10 and x=3
Step-by-step explanation:
This equation can be solved through factoring. However, there is one step that must happen first.
First, subtract 30 from both sides
Then, factor using the knowledge that the 2 factors will add to 7 and multiply to -30.
Next, using the zero product property, set each expression to zero.
Finally, solve each of these equations for x.
