(2k² + 5k - 6)(3k - 1)
(6k³ - 2k² + 15k² - 5k - 18k + 6)
6k² + 13k² - 23k + 6

Which solution to the equation StartFraction 1 Over x minus 1 EndFraction = StartFraction x minus 2 Over 2 x squared minus 2 End

Darina [25.2K]

Answer:

x = - 4

Step-by-step explanation:

Given the expression

$\frac{1}{x-1} = \frac{x-2}{2x^2-2}$

This can also be expressed as;

$\frac{1}{x-1} = \frac{x-2}{2(x-1)(x+1)}\\1 = \frac{x-2}{2(x+1)}$

Cross multiply

$2(x+1) = x - 2\\2x+2 = x-2$

Add 2 to both sides

$2x+2+2 = x-2+2\\2x+4 = x\\2x-x = -4\\x = -4$

Hence the required extraneous solution is x = -4
