Question

Which polynomial represents the sum below (4x^2+1)+(4x^2+x+2)

Answer 1

8x^2 + x + 3.

Explanation:

(4x^2+1)+(4x^2+x+2)

= 8x^2 + x + 2 + 1

= 8x^2 + x + 3.

Answer 2

The polynomial
`8x^2+x+3` represents the sum of given expression.

Explanation:

The given expression is

`(4x^2+1)+(4x^2+x+2)`

We need to find the sum of given polynomials.

Open the brackets.

`4x^2+1+4x^2+x+2`

Combine like terms.

`(4x^2+4x^2)+x+(1+2)`

On further simplification we get

`8x^2+x+3`

Therefore the polynomial
`8x^2+x+3` represents the sum of given expression.
