The factors of x^2 - 18x + 32 have to be determined. If the roots of x^2 - 18x + 32 = 0 are x1 and x2, the factors of the given expression are (x - x1) and (x - x2)

Use the formula to calculate the roots of the quadratic equation.

x1 = 18/2 + sqrt(196)/2

=> 9 + 7

=> 16

x2 = 9 - 7 = 2

The factors of x^2 - 18x + 32 are (x - 16) and (x - 2)
