[tex]4x^2-x^5+6x^3[/tex]
The leading coefficient is the number written in front of the variable with the highest exponent
The highest exponent is 5, hence the leading coefficient is the coefficient of x raised to power 5, this is equal to -1
The polynomial can be written as
[tex]-1x^5+6x^3+4x^2[/tex]Leading coefficient is ;
[tex]-1[/tex]
