<u>Answer</u>:

\boxed{x = \frac{1}{2}} \text{and} \boxed{x = - 1}

<u>Step-by-step explanation:</u>

The quadratic formula is: $\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

So plugging in all the values, we are left with \frac{-1 \pm 3}{4}.

Then, we can solve for both values of x, which are x = 1/2 and x = -1
