Answer:
r = -2
s = 13
Step-by-step explanation:
Given quadratic equation is,
11x² - 44x - 99 = 0
Divide this equation by 11,
x² - 4x - 9 = 0
x² - 2(2)x - 9 = 0
x² -2(2)x + 2² - 2² - 9 = 0
[x² - 2(2)x + 2²] - 4- 9 = 0
(x - 2)² - 13 = 0
(x - 2)² = 13
[x + (-2)]² = 13
By comparing this equation with (x + r)² = s
Values of the constants r and s will be,
r = (-2) and s = 13
