\left(x-5\right)\left(x-3\right)\left(x-2\right)-\left(x-6\right)\left(x-3\right)\left(x-2\right)=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Variable x cannot be equal to any of the values 2,3,5,6 since division by zero is not defined. Multiply both sides of the equation by \left(x-6\right)\left(x-5\right)\left(x-3\right)\left(x-2\right), the least common multiple of x-6,x-5,x-3,x-2.
\left(x^{2}-8x+15\right)\left(x-2\right)-\left(x-6\right)\left(x-3\right)\left(x-2\right)=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Use the distributive property to multiply x-5 by x-3 and combine like terms.
x^{3}-10x^{2}+31x-30-\left(x-6\right)\left(x-3\right)\left(x-2\right)=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Use the distributive property to multiply x^{2}-8x+15 by x-2 and combine like terms.
x^{3}-10x^{2}+31x-30-\left(x^{2}-9x+18\right)\left(x-2\right)=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Use the distributive property to multiply x-6 by x-3 and combine like terms.
x^{3}-10x^{2}+31x-30-\left(x^{3}-11x^{2}+36x-36\right)=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Use the distributive property to multiply x^{2}-9x+18 by x-2 and combine like terms.
x^{3}-10x^{2}+31x-30-x^{3}+11x^{2}-36x+36=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
To find the opposite of x^{3}-11x^{2}+36x-36, find the opposite of each term.
-10x^{2}+31x-30+11x^{2}-36x+36=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Combine x^{3} and -x^{3} to get 0.
x^{2}+31x-30-36x+36=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Combine -10x^{2} and 11x^{2} to get x^{2}.
x^{2}-5x-30+36=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Combine 31x and -36x to get -5x.
x^{2}-5x+6=\left(x-6\right)\left(x-5\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Add -30 and 36 to get 6.
x^{2}-5x+6=\left(x^{2}-11x+30\right)\left(x-2\right)-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Use the distributive property to multiply x-6 by x-5 and combine like terms.
x^{2}-5x+6=x^{3}-13x^{2}+52x-60-\left(x-6\right)\left(x-5\right)\left(x-3\right)
Use the distributive property to multiply x^{2}-11x+30 by x-2 and combine like terms.
x^{2}-5x+6=x^{3}-13x^{2}+52x-60-\left(x^{2}-11x+30\right)\left(x-3\right)
Use the distributive property to multiply x-6 by x-5 and combine like terms.
x^{2}-5x+6=x^{3}-13x^{2}+52x-60-\left(x^{3}-14x^{2}+63x-90\right)
Use the distributive property to multiply x^{2}-11x+30 by x-3 and combine like terms.
x^{2}-5x+6=x^{3}-13x^{2}+52x-60-x^{3}+14x^{2}-63x+90
To find the opposite of x^{3}-14x^{2}+63x-90, find the opposite of each term.
x^{2}-5x+6=-13x^{2}+52x-60+14x^{2}-63x+90
Combine x^{3} and -x^{3} to get 0.
x^{2}-5x+6=x^{2}+52x-60-63x+90
Combine -13x^{2} and 14x^{2} to get x^{2}.
x^{2}-5x+6=x^{2}-11x-60+90
Combine 52x and -63x to get -11x.
x^{2}-5x+6=x^{2}-11x+30
Add -60 and 90 to get 30.
x^{2}-5x+6-x^{2}=-11x+30
Subtract x^{2} from both sides.
-5x+6=-11x+30
Combine x^{2} and -x^{2} to get 0.
-5x+6+11x=30
Add 11x to both sides.
6x+6=30
Combine -5x and 11x to get 6x.
6x=30-6
Subtract 6 from both sides.
6x=24
Subtract 6 from 30 to get 24.
x=\frac{24}{6}
Divide both sides by 6.
x=4
Divide 24 by 6 to get 4.
