Since the figure is a rectangle
SQ = PR
11x-26 = 5x +28
6x = 54
x = 9

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

Leading coefficient is ;
