Polynomial are mathematical expressions involving variables raised with non-negative integers and coefficients. The correct option is C.
What is a polynomial?
Polynomial are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.
Example:
x² + 3x + 5
As per the given tile diagram, the first polynomial is,
First polynomial = 5x² + 4x + 6
The second polynomial equal is,
Second polynomial = 2x² + 2x + 1
Now, the sum of the two polynomial can be written as,
Sum = 5x² + 4x + 6 + 2x² + 2x + 1
= 7x² + 6x + 7
Hence, the correct option is C.
