Solve for x - 1/x+1 +2/x+2=4/x+y,x≠-1,-2,-4? |
| Answer» {tex}\\frac { x + 1 } { x - 1 } + \\frac { x - 2 } { x + 2 } = 4 - \\frac { 2 x + 3 } { x - 2 } {/tex}{tex}\\frac { x ^ { 2 } + 3 x + 2 + x ^ { 2 } - 3 x + 2 } { x ^ { 2 } + x - 2 }{/tex}\xa0=\xa0{tex}\\frac { 4 x - 8 - 2 x - 3 } { x - 2 }{/tex}(2x2\xa0+ 4) (x - 2) = (2x -11 ) (x2\xa0+ x - 2)or, 5x2\xa0+ 19x- 30 = 0or, (5x - 6) (4x - 5) = 0or, x = {tex}\\frac{5}{4}{/tex},\xa0{tex}\\frac 65{/tex} | |
