For this case, the first thing we must do is to count similar terms.
We have then:
Polynomial 1:
x ^ 2 = 2
x = 1
1 = 3
The polynomial is:
2x ^ 2 + x + 3
Polynomial 2:
x ^ 2 = 1
x = 3
1 = 4
The polynomial is:
x ^ 2 + 3x + 4
Adding we have:
(2x ^ 2 + x + 3) + (x ^ 2 + 3x + 4)
x ^ 2 (2 + 1) + x (1 + 3) + (3 + 4)
3x ^ 2 + 4x + 7
Answer:
3x ^ 2 + 4x + 7
option B
