Answer: 103/15
Step-by-step explanation:
We can simplify the right-hand side to be .
This means we need to solve:
Given a quadratic equation 
1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.
In our case the coefficient of x is 10, so we write 10 as 2*5
2. then we write +
and - to the expression:
