Answer 1

x² - 14x + 40 = 0

To complete the square, recognize that the factor will be x - 7. If this is squared, we have: x² - 14x + 49

To balance the equation, we have to add 9 to the right hand side, so we have:

x² - 14x + 49 = 9

Take the square root:

x - 7 = 3 <<edit: should be +/- 3>>

So:

x = 10, or 4
