Question

Solve quadratic equation:

x+2/x+1 = x+2/1-x - 4/x-1

Domain is - x1 =/= 1 ; x2 =/= -1

Help me solve it? In my country we have to multiply the numerators with the greatest common factors (that are from the denominators) and reach to a solution with x1 and x2 with the quadratic equation formula -b +- sqrt b^2 - 4ac/ 2a.

Please help!!

Answer 1

\[\frac{ x+2 }{ x+1 } = \frac{ x+2 }{ 1-x} - \frac{ 4 }{ x-1 }\]

Answer 3

thank you. do you know how to solve this? :/

Answer 4

(1-x) 0r (x-1) is the same @galaxy-fanfan

Answer 5

\[\frac{ x+2 }{ x-1 }=\frac{ x+2-4 }{ x-1 }\]

Answer 6

\[\frac{ x+2 }{ x-1 }=\frac{ x-2 }{ x-1 }\]

Answer 7

do cross method @galaxy-fanfan

Answer 8

one approach
first multiply x +2/1-x by -1/-1
this will change the denominator to (x -1) and the numerator to -x -2
rewrite the original with this

thnx @triciaal
