Question

Solve for x: x-2/x-1 - x+4/2x+2= 0​

Answer 1

Answer:

Step by step solution :

STEP

1

:

Equation at the end of step 1

(((x4) - 2x2) - x) - 1 = 0

STEP

2

:

Checking for a perfect cube

2.1 x4-2x2-x-1 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: x4-2x2-x-1

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -x-1

Group 2: x4-2x2

Pull out from each group separately :

Group 1: (x+1) • (-1)

Group 2: (x2-2) • (x2)
