Q:

Solve the following equation. Remember to check for extraneous solutions 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).

Accepted Solution

A:
Answer:-1, 2, 6Step-by-step explanation:We have to solve the equation as follows: 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).Now, we have, [tex]\frac{1}{x-6} +\frac{x}{x-2} = \frac{4}{x^{2}-8x+12 }[/tex]⇒[tex]\frac{(x-2)+x(x-6)}{(x-2)(x-6)} = \frac{4}{x^{2}-8x+12 }[/tex]⇒[tex]\frac{x-2+x^{2}-6x }{(x-2)(x-6)} =\frac{4}{(x-2)(x-6)}[/tex]⇒[tex]\frac{(x-2)(x-6)}{x^{2}-5x-2 }=\frac{(x-2)(x-6)}{4}[/tex]⇒[tex](x-2)(x-6)[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0[/tex]⇒ [tex](x-2)(x-6) =0[/tex] or, [tex][\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0[/tex]If, (x-2)(x-6) =0, then x=2 or x=6If, [tex][\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0[/tex], then [tex]x^{2} -5x-2=4[/tex]and (x-6)(x+1) =0Therefore, x=6 or -1So the solutions for x are -1, 2 6.
