Question

Written as a simplified polynomial in standard form, what is the result when

(x + 5)2 is subtracted from 9x?

Answer 1

7x-10

Explanation:

9x-(x+5)2

Apply the distributive property.

9x+(-x-1⋅5)⋅2

Multiply -1 by 5.

9x+(-x-5)2

Apply the distributive property.

9x−x⋅2−5⋅2

Multiply 2 by −1.

9x−2x−5⋅2

Multiply −5 by 2.

9x-2x-10

Subtract 2x from 9x.
