If x – 9 is a factor of x2 – 5x – 36, what is the other factor?

x – 4
x + 4
x – 6
x + 6

If x – 9 is a factor of x² – 5x – 36 than the other factor is x + 4 .

Step-by-step explanation:

As given the expression is given in the form be as follow .

x²– 5x – 36 = 0

Simplify the above equation

x² - 9x + 4x - 36 = 0

x (x - 9)+ 4 (x -9) = 0

(x - 9)(x + 4) = 0

Therefore the If x – 9 is a factor of x² – 5x – 36 than the other factor is x + 4 .

the correct answer is d
