The polynomial 7x² + 6x + 7 is equal to the sum of polynomials 1 and 2.
Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved. Example, x² + 3x + 5.
As per the given informations, the first polynomial is 2x² + 2x + 1.
The second polynomial equal is 5x² + 4x + 6.
Now, the sum of the two polynomial can be written as,
Sum = 5x² + 4x + 6 + 2x² + 2x + 1 = 7x² + 6x + 7
Therefore, the polynomial 7x² + 6x + 7 is equal to the sum of polynomials 1 and 2.
