Find the sum: (x2 + 2x + 3) + (3x2+x+1)

O A. 4x + 4x + 3

O B. 3x4 + 4x+3

O C. 4x2+3x+4

O D. 4x2 + 3x+4

For apex!

C/D, which you wrote the same answer.

4x² + 3x + 4

Step-by-step explanation:

The two polynomials are added, so we can remove the brackets:

(x² + 2x + 3) + (3x² + x + 1)

= x² + 2x + 3 + 3x² + x + 1

= x² + 3x² + x + 2x + 1 + 3 <=rearrange by like terms (same variable)

= 4x² + 3x + 4 <=after collecting like terms
