X-2 reduction of 3x-6

First, change the denominator to 3 (x minus 2), and then reduce it to the numerator, leaving only one-third

Simplification: x ^ 2 + 5x + 6 / x + 2

:x^2+5x+6/x+2
=(x+2)(x+3)/(x+2)
=x+3

Simplification: 6 / (x ^ 2-9) + 1 / (x + 3)

Original formula = 6 / ((x-3) * (x + 3)) + 1 / (x + 3)
=6/（(X-3)*（X+3））+(X-3)/（(X-3)*（X+3））
=(6+(X-3))/（(X-3)*（X+3））
=(X+3)/((X-3)*(X+3))
=1/(X-3)
