Question

What is the difference of the two polynomials?

Answer 1

Answer:

(A)$7x^2+5x$

Step-by-step explanation:

Given:The given expression is:

$(9x^2+8x)-(2x^2+3x)$

To find: The difference of the two polynomials.

Solution: The given expression is:

$(9x^2+8x)-(2x^2+3x)$

Upon solving the above equation, we get

$9x^2+8x-2x^2-3x$

Combining the like terms and then solving,

$9x^2-2x^2+8x-3x$

$7x^2+5x$

which is the required difference.

Hence, option A is correct.

Answer 2

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