Subtract these polynomials.
(2x2 + 4x + 3) - (4x2 - 2x-3) =
o a. - 2x2 + 2x+0
o b. 6x2 + 6x + 6
o c. 6x2+2x+ 0
o d.-2x2+68+6

B.   -2x2 + 6x + 6.

Step-by-step explanation:

(2x2 + 4x + 3) - (4x2 - 2x-3)   Distribute negative over the parentheses:

= 2x2 + 4x + 3 - 4x2 + 2x + 3

= 2x2 - 4x2 + 4x + 2x + 3 + 3

=  -2x2 + 6x + 6.

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
