Question

Degree of the polynomial( t³+ 7) (3 - t³) is​

Answer 1

Answer:

on multiplication

3t³ - t⁶ + 21 -7t³

= -t⁶ -4t³ + 21

degree = 6

Answer 2

Answer:

The degree of polynomial is 6.

Step-by-step explanation:

The degree of a polynomial is the power of its highest variable

We are given the polynomial ( t³+ 7) (3 - t³) 

If we pay close attention we can see that there are 2 terms in multiplication

So if we try to opeen the brackets, each term inside will be multiplied with the quantity out side the bractket

We  can also observe that there is t³ in both the brackets

So when we open it these elements will be multiplied and we will get a element with 6th power of t

This essentially means 6 is the degree of polynomial.
