You subtract the like terms, don't forget to distribute the subtraction sign, its 7x2+5x

Answer:

(A)[tex]7x^2+5x[/tex]

Step-by-step explanation:

Given:The given expression is:

[tex](9x^2+8x)-(2x^2+3x)[/tex]

To find: The difference of the two polynomials.

Solution: The given expression is:

[tex](9x^2+8x)-(2x^2+3x)[/tex]

Upon solving the above equation, we get

[tex]9x^2+8x-2x^2-3x[/tex]

Combining the like terms and then solving,

[tex]9x^2-2x^2+8x-3x[/tex]

[tex]7x^2+5x[/tex]

which is the required difference.

Hence, option A is correct.
