Correct Question:
Which term could be put in the blank to create a fully simplified polynomial written in standard form?
Options
Answer:
Step-by-step explanation:
Given
Required
Fill in the missing gap
We have that:
From the polynomial, we can see that the power of x starts from 3 and stops at 0 while the power of y is constant.
Hence, the variable of the polynomial is x
This implies that the power of x decreases by 1 in each term.
The missing gap has to its left, a term with x to the power of 3 and to its right, a term with x to the power of 1.
This implies that the blank will be filled with a term that has its power of x to be 2
From the list of given options, only can be used to complete the polynomial.
Hence, the complete polynomial is:
