Answer:

[tex]2x+3[/tex]/[tex]2x-3[/tex]

Step-by-step explanation:

firstly we make two steps to simplify this question.

1st step: simplify [tex]2x^{2} +5x+3[/tex]

to simplify this we use factorization

[tex]2x^{2} +2x+3x+3[/tex]

[tex]2x(x+1) +3(x+1)[/tex]

[tex](2x+3) (x+1)[/tex]        .....(1)

2nd step:simplify [tex]2x^{2} -x-3[/tex]

[tex]2x^{2} +2x-3x-3[/tex]

[tex]2x(x+1)-3(x+1)[/tex]

[tex](2x-3)(x+1)[/tex]          .....(2)

now dividing (1) and  (2), we get the answer

[tex]2x+3/2x-3[/tex]
