Answer:

x = 2

and

x = 3

Step-by-step explanation:

The function given is:

[tex]y=\frac{3x+6}{x^2-5x+6}[/tex]

In this fraction, the bottom part is the denominator. We need to set it equal to 0 and solve for 2 values of x.

[tex]x^2-5x+6=0\\x^2-3x-2x+6=0\\x(x-3)-2(x-3)=0\\(x-2)(x-3)=0\\x=2,3[/tex]

This is middle term factorization process. Hence the 2 solutions (roots) of the denominator is:

x = 2, 3
