Answer:
A
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent in the terms of the polynomial. The leading coefficient is the coefficient of the term with the largest exponent.
Given
f(x) = 2x³ + 2x² -
The term - means that f(x) is not a polynomial
Since terms with division by a variable are not allowed.
Answer:

Step-by-step explanation:
Expand both factors and collect like term
Using Pascal' triangle with n = 6 to obtain the coefficients
1 6 15 20 15 6 1
Decreasing powers of 1 from to
Increasing powers of 3x from to
= 1. + 6.
+ 15.
+ 20.
+ 15.1²
+ 6.
+ 1.
= 1 + 18x + 135x² + 540x³ + 1215 + 1458
+ 729
--------------------------------------------------------------------------------------
= 1. + 6.
+ 15.
+ 20.
+ 15.1²
+ 6.
+ 1.
= 1 - 18x + 135x² - 540x³ + 1215 - 1458
+ 729
----------------------------------------------------------------------------------
Collecting like terms from both expressions
+
= 2 + 270x² + 2430 + 1458

Using Pascal's triangle with n = 5
1 5 10 10 5 1
Decreasing powers of 1 from to
Increasing powers of 2x from to
= 1. + 5.
+ 10.

+ 1.
= 1 + 10x + 40x² + 80x³ + 80 + 32
If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.
Example 1:
Here, since the numerator is a fraction, it is a complex fraction.
Example 2:
Here, since the numerator and the denominator are fractions, it is a complex fraction.
