1. Find roots of the equation `(5X-18)/(X+2) = (2X-6)/(X-1)`
` (5X-18)/(X+2) = (2X-6)/(X-1)`
` => (5X-18)*(X-1) = (2X-6)*(X+2)`
` => 5X^2-23X+18 = 2X^2-2X-12`
` => 3X^2-21X+30 = 0`
` => (3X^2-21X+30) = 0`
` => 3X^2-21X+30 = 0`
` => 3(X^2-7X+10) = 0`
` => 3(X^2-2X-5X+10) = 0`
` => 3(X(X-2)+(-5)(X-2)) = 0`
` => 3(X-5)(X-2) = 0`
` => (X-5) = 0" or "(X-2) = 0`
` => X = 5" or "X = 2`
