Subtract these polynomials. (3x^22+2x+4)-(x^2+2x+1)

3x^22−x^2+3

Step-by-step explanation:

Let's simplify step-by-step.

3x^22+2x+4−(x2+2x+1)

Distribute the Negative Sign:

=3x^22+2x+4+−1(x2+2x+1)

=3x^22+2x+4+−1x2+−1(2x)+(−1)(1)

=3x&22+2x+4+−x2+−2x+−1

Combine Like Terms:

=3x22+2x+4+−x2+−2x+−1

=(3x22)+(−x2)+(2x+−2x)+(4+−1)

=3x22+−x2+3

=3x22−x2+3

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
