Answer:

9 and -4

Step-by-step explanation:

change the word form to math form so now

x² - 36 = 5x     This look like a factoring problem, so we put it equal to 0

x² - 5x - 36 = 0     Now factor

(x - 9) (x + 4)     We have to find 2 numbers that give -36 when we multiply and -5x when we add

x - 9 = 0

x = 9

x + 4 = 0

x = -4

you can check by plugin the x value to actual equation.
