When m is the value, the fractional equation 1 / X-1 + m / X-2 = 2m + 2 / x ^ 2-3x + 2 has an increasing root

When m is the value, the fractional equation 1 / X-1 + m / X-2 = 2m + 2 / x ^ 2-3x + 2 has an increasing root

1 / (x-1) + m / (X-2) = (2m + 2) / (x-1) (X-2) multiply both sides by (x-1) (X-2) X-2 + m (x-1) = 2m + 2 to increase the root, that is, the common denominator is 0 (x-1) (X-2) = 0x = 1, x = 2x = 1 to substitute X-2 + m (x-1) = 2m + 2-1 = 2m + 2m = - 3 / 2x = 2 to substitute X-2 + m (x-1) = 2m + 20 + M = 2m + 2m = - 2, so m = - 3 / 2, M = - 2
