( x² + 2 x + 1 ) / ( x - 2 ) / ( x² - 1 ) / ( x² - 4 ) =
= ( x² + 2 x + 1 )·( x² - 4 ) / ( x - 2 )·( x² - 1 ) =
= ( x + 1 )²·( x - 2 )·( x + 2 ) / ( x - 2 )·( x - 1 )·( x + 1 ) =
= ( x + 1 )·( x + 2 ) / ( x - 1 )
Answer:
-5 & 1
Step-by-step explanation:
[x² + 2(x)(2) + 2²] - 2² - 5 = 0
(x+2)² - 4 - 5 = 0
(x+2)² = 9
x+2 = +/- 3
x+2 = 3 x = 1
x+2 = -3 x = -5
