6x
42/6 = 7 (valid), 18/6 = 3 (valid), 12/6 = 2 (valid)
7, 8, 9, 10, and 11 are all not divisible by 12, and 12 is not divisible by 18, so 6 is the highest number. 
Also, each number has at least one x, so you can take one out. 
Remaining=
6x (7 + 3x^2 + 2x^3)

Answer:
The leading coefficient of the polynomial is 5 .
Step-by-step explanation:
f(x) = 6x^5 + 9x^4 + 2x^3 + 3x^2 - 4x -6
In this polynomial , the highest exponential is the leading coefficient . 
So there are 5 coefficients , 
5 , 4 , 3 , 2 , and x
so above , the highest one is 5 .
