What is the leading term, leading coefficient, and degree of this polynomial F(X)=56x+3x2−4.3x3−7x4?

Explanation:
The leading term of a polynomial is the term of highest degree.
The leading coefficient of a polynomial is the coefficient of the leading term.
The degree of a polynomial is the degree of the leading term.
${\displaystyle -7x^4\Rightarrow }$ the leading term
${\displaystyle -7\Rightarrow }$ the leading coefficient
${\displaystyle 4\Rightarrow }$ the degree of this polynomial
