Answer:

Step-by-step explanation:
1. Subtract 9 from both sides of the equation:

2. Notice that the coefficient of "x" is 7. Then:

3. Add
to both sides of the equation:

4. Completing the square, you get:

5. To find the solutions, you must square-root both sides of the equation, simplify, and solve for "x". Then, you get:

Simplify the problem down, so:
m = 12 & n = 5
m = 6 & n = 2.5 <span>(divided each number by 20)
</span>
Now m is a factor of 18. Multiply each number by 3.
Answer: m = 18 & <span>n = 7.5</span>
