Question

Which polynomial represents the sum below? (4x^2+6) + (2x^2+6x+3)

Answer 1

Answer:

Option D -  $(4x^2+6)+(2x^2+6x+3)=6x^2+6x+9$

Step-by-step explanation:

Given : Polynomial $(4x^2+6) + (2x^2+6x+3)$

To find : Which polynomial represents the sum below?

Solution :

Step 1 - Write the polynomial

$(4x^2+6)+(2x^2+6x+3)$

Step 2 - Open the parenthesis,

$=4x^2+6+2x^2+6x+3$

Step 3 - Add like terms,

$=6x^2+6x+9$

Therefore, Option D is correct.

$(4x^2+6)+(2x^2+6x+3)=6x^2+6x+9$

Answer 2

D. Add like terms.
So 4x^2+2x^2=6x^2
6x is only x term
6+3=9

So D. 6x^2+6x+9
