Answer:
This equation has two solutions.
1 solution is: x - 1
Solution #2 is : x - 7
Step-by-step explanation:
1. Move the constant to the left. We end up with x^2 - 8x +7 = 0
2. Rewrite the expression: x^2 - x - 7x + 7 = 0
3. Factor the expressions: x * (x-1) -7(x-1) = 0
4. Separate into possible cases : (x-1) * (x-7) = 0
5. Solve the equation(s): x-1 = 0
x-7 = 0
6. Possible solutions are as follows: x-1 OR x-7
