Answer:
Part A) The polynomial has three terms
Part B) The terms are 
Part C) Is a 2nd degree polynomial
Part D) The name of the polynomial is a 2nd degree trinomial
Step-by-step explanation:
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
we have

The polynomial has three terms
The terms are

therefore
The polynomial is a trinomial
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
The term is 
The highest exponent is the 2 so this is a 2nd degree polynomial
therefore
The name of the polynomial is a 2nd degree trinomial
Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.
Since -1 is less than or equal to -1 you input it into the first equation.
-3•(-1) -4
3-4
-1
the answer is -1 good luck
The x-coordinate of the solution. 1
