Answer:

[tex]7x^{2} +9x-8[/tex]  in square feet

Step-by-step explanation:

we have that

The total area of the park is ---->  [tex]9x^{2} +4x-5[/tex]

The area of the park designated for  soccer fields is --> [tex]2x^{2} -5x+3[/tex]

we know that

To find out the area of the park that is not designated for soccer fields, subtract the area of the park designated for  soccer fields from the total area of the park

so

[tex]9x^{2} +4x-5-(2x^{2} -5x+3)[/tex]

Remove the parenthesis

[tex]9x^{2} +4x-5-2x^{2}+5x-3[/tex]

Combine like terms

[tex]7x^{2} +9x-8[/tex]
