elena-14-01-66 [18.8K]

The polynomial that represent twice the sum of -5x^{2} - x +6 and 7x^{2} + x -1 is : 4x^{2}+10

<h3>What is a polynomial?</h3>

A polynomial is any  algebraic expression that has the least value of the power of  its variable as 2.

When the highest value of the polynomial is 2, it is a called a quadratic expression.

Analysis:

2( -5x^{2} -x +6 + 7x^{2} +x -1)

2( 2x^{2} + 5) =

4x^{2} + 10

In conclusion, the polynomial that represents the above  expressions is 4x^{2} + 10
