After simplifying the expression, what is the numerator?

a
−x2 + 4x + 2

b
3x2 + x − 2

c
−3x2 − 4x + 2

d
3x2 + x − 4

3x^2 +x-4

Step-by-step explanation:

x+1         x+2

-

2            3x

The common denominator  is 6x so multiply the first term by 3x/3x and the second term by 2/2

x+1    3x           x+2        2

*     - *

2       3x           3x         2

3x^2+3x            2x+4

-

6x                      6x

Combine terms

3x^2 +3x -2x-4

6x

3x^2 +x-4

6x

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
