Determine whether the set, together with the indicated operations, is a vector space. If it is not, then identify one of the vector space axioms that fails. The set of all seventh-degree polynomials with the standard operations

Following are the solution to this question:

Step-by-step explanation:

Let X is a set of all polynomials of the third-degree with regular operations.  

This set is not a space for a vector since it is not shut down  

For instance:

Calculating the sum:

That's why X isn't a space for vectors because X isn't shut down.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
