Answer:
Step-by-step explanation:
You can solve this equation with the quadratic formula which is:
All you need to do is rearrange the equation (add to both sides and then multiply both sides by 2) to get:
From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:
That simplifies to:
Which simplifies even further to:
Which gets you:
