Solve: 1/x-1 + 2/x = x/x-1
Rational Equation

1%2F%28x+-+1%29+%2B+2%2Fx+=+x%2F%28x+-+1%29

** Note that x+%3C%3E+1, or x+%3C%3E+0, since these values would render fractions in the equation as UNDEFINED.

x+%2B+2%28x+-+1%29+=+x%5E2 ------ Multiplying by LCD, x(x - 1)

x+%2B+2x+-+2+=+x%5E2

3x+-+2+=+x%5E2

x%5E2+-+3x+%2B+2+=+0

(x - 1)(x - 2) = 0

x = 1 = 0, or x = 1

As explained above, x+%3C%3E+1, so

x - 2 = 0, or highlight_green%28x+=+2%29

You can do the check!!
