What is the coefficient of the second highest term in the expression: 
?
What is the coefficient of the second highest term in the expression: 
Step 1: Rearrange the terms from highest power to lowest power.
We will get: 
.
Step 2: We count the second term from starting from the left since it is the second highest term in the rearranged expression.
Step 3: Isolate the term.
The second term is 
Step 4: Find the coefficient. The coefficient of a term is considered as the number before any variables. In this case, the coefficient is 
.
So, the answer is

Simplify the polynomial
.
How many terms does the simplified form have?
Simplify the polynomial
How many terms does the simplified form have?
Arrange and combine like terms (those with the same variable) as follows:
Since each term now has a different exponent for the variable, no further combining is possible. The simplified form has four terms.
