Answer:
The 2 factors are -2 and 18.
Step-by-step explanation:
xy = -36
Let y = 0.5x - 11 so
x(0.5x - 11) = -36
0.5x^2 - 11x + 36 = 0
0.5(x^2 - 22x + 72) = 0
(x - 4)(x - 18) = 0
x = 4, 18.
Try x = 18:-
The 2 numbers which are factors of -36 must be -2 and 18 because they fit the requirement that 0.5(18) - 11 = 9 - 11 = -2.
