We need another number, we can't find the greatest common factor of one number :)
The solutions are where the quadratic is equal to 0, or when the quadratic crosses the x axis.
Where the quadratic crosses the x axis are the solutions:
6) x = –5, x = –6
7) x = 0, x = 1
8) x = –6, x = 1
9) x = –4, x = –3

Substitute the value of the variable into the equation and simplify
66xh
Any percentage is the number divided by 100. So, 4% is 4/100. That can be simplified to 1/25.
