Complete the square:
x^2 + 20x − 44 = 0
x^2 + 20x = 44
Add 100 (which is (20/2)^2) to both sides:
(x + 10)^2 = 144
x + 10 = ±12
x = 2 or x = −22
Answer: x = −22, x = 2.
x^2 + 20x − 44 = 0
x^2 + 20x = 44
Add 100 (which is (20/2)^2) to both sides:
(x + 10)^2 = 144
x + 10 = ±12
x = 2 or x = −22
Answer: x = −22, x = 2.
