This equation doesn't factor, so the quadratic formula is probably the best choice for how to solve it.
The quadratic formula is:

This formula assumes you know that the equation needs to be in
the form of .
For your equation:
a = 2
b = -7
c = -3
So, when you plug in the a, b and c, you get:

When you simplify the information under the square root and in the denominator, you get:

Then:

Then simplify the square root.
This leaves you with:

This can be your final two answers, unless it needs to be in decimal form and that requires a calculator or square root table.
