Hey mate here we go

lets \: write \: eq \\  \frac{x(x - 1) - (m + 1)}{(x - 1)(m - 1)}  =  \frac{x}{m}  \\ cross \: multiplication \\ m(x(x - 1) -(m  +  1))  \\ = x((x - 1)(m - 1)) \\  \\ m {x}^{2}  - mx -  {m}^{2}  - m  \\ = {x}^{2}m - {x}^{2}  - xm + x \\ now \: canclation \: both \: side \: we \: will \: have \:  \\  -  {m}^{2}  - m =   - {x}^{2}  + x \\  - m(m +1)  =  - x(x - 1) \\  \\ therefore \:  \\  - m(m + 1) = 0 \\  - m = 0 \:  \:  \:  \:  \:  \:  \:  \:  \: (m + 1 = 0 \:  \:  \: m =  - 1) \\ \\   - x(x - 1) = 0 \\   - x = 0 \:  \:  \:  \: x - 1 = 0  \:  \:  \: \: x = 1

I hope this will helps you

technicalboyak: Why -m(m+1) = 0 ???
veerukhugar: that's should be equated to zero

Answer:

m = -1/2

Step-by-step explanation:

( x(x - 1) - (m + 1))/ (x - 1)(m - 1) = x/m

=> mx(x-1) - m(m+1) = x(x-1)(m-1)

=> x(x-1)(m-(m-1) - m(m+1) = 0

=> x(x-1) - m(m+1) = 0

=> x² - x  - m(m+1) = 0

roots are equal if

D = 0 = b² - 4ac

(-1)² - 4(1)(-m(m+1)) = 0

=> 1 + 4m² + 4m = 0

=> 4m² + 2m + 2m + 1 = 0

=> 2m(2m +1) + 1(2m+1) = 0

=> (2m+1)² = 0

=> m = -1/2
