Let the given Equation be x^2 - 9x + 14 = 0
x^2 - 2x - 7x + 14 = 0
x(x - 2) - 7(x - 2) = 0
(x - 2)(x - 7) = 0
x = 2,7.
When x = 2:
f(2) = (2)^2 - 9(2) + 14 = 0
= 4 - 18 + 14 = 0
0 = 0.
f(7) = (7)^2 - 9(7) + 14 = 0
= 49 - 63 + 14 = 0
-14 + 14 = 0
0 = 0.
Therefore (2,7) is the correct solution to the equation x^2 - 9x + 14 = 0.
Hope this helps!
