Answer:
x² - 11x + 28 = (x - 4)(x - 7)
x = 4 or x = 7
Explanation:
Factor: x² - 11x + 28
We need 2 numbers that multiply to 28 and add to -11.
The numbers are -4 and -7.
x² - 11x + 28 = (x - 4)(x - 7)
If the problem is to solve the equation: x² - 11x + 28 = 0, then continue as follows:
x² - 11x + 28 = 0
(x - 4)(x - 7) = 0
x - 4 = 0 or x - 7 = 0
x = 4 or x = 7
