General form of polynomial:
“1. The general form of the polynomial is given by
2. If
Calculation:
The given polynomial
The polynomial
Therefore, the polynomial
(b)
To give: The leading coefficient of the polynomial
Answer to Problem 1TE
The leading coefficient of the polynomial
Explanation of Solution
From the polynomial
By the above definition (2), it is known that if
Therefore, the leading coefficient is 3 which is the coefficient of highest degree term.
