we have the expression

[tex]\frac{12x^2+31x+9}{3x^2-5x-2}[/tex]

Remember that

the denominator can not be equal to zero

so

Find the roots of denominator

using a graphing tool

[tex]3x^2-5x-2=0[/tex]

the roots are

x=-1/3 and x=2

that means

[tex]3x^2-5x-2=3(x+\frac{1}{3})(x-2)[/tex]

the restrictions are x=-1/3 and x=2
