Step 1: Factor the numerator and denominator completely.
Step 2: Cancel (divide) out common factors
Simplify the following rational expressions: ( Can you please show the steps, thank you.)
x² - 1
_________
2x²- x - 1
6x² + 4x
_________
2x² + 4x
Step 2: Cancel (divide) out common factors
Simplify the following rational expressions: ( Can you please show the steps, thank you.)
x² - 1
_________
2x²- x - 1
6x² + 4x
_________
2x² + 4x
-
x² - 1 (x - 1) ( x +1)
_____=____________ << cancel (x -1)>> then the answer is
2x²- x - 1 (x - 1) ( 2x +1)
(x + 1)
---------
(2x + 1)
6x² + 4x 2x (3x +2)
_____ = ------------------ << cancel 2x >> then the answer is
2x² + 4x 2x (x+2)
(3x +2)
----------
(x+2)
_____=____________ << cancel (x -1)>> then the answer is
2x²- x - 1 (x - 1) ( 2x +1)
(x + 1)
---------
(2x + 1)
6x² + 4x 2x (3x +2)
_____ = ------------------ << cancel 2x >> then the answer is
2x² + 4x 2x (x+2)
(3x +2)
----------
(x+2)
