Factor first x^2 + 3x + 2 = (x+1)(x+2)

5x + 10 = 5(x+2)

then (x+1)(x+2) / 5(x+2) = (x+1) / 5 for all x not = -2

X^2+3x+2 / 5x+10

(x+2)(x+1) / (5(x+2))

(x+1)/5

X^2+3x+2 / 5x+10

is not the same as

(x^2+3x+2) / (5x+10)

The first one would be difficult to simplify.

[ x^3 + ( 15 x ^2 + 2 ) + 10x ] / 5x
[ x^3 + 15 x ^2 + 10 x + 2 ]/ 5x

(x+2)(x+1)/5(x+2)

(x+2) cancels

(x+1)/5

Also x must not equal -2
