SUMMARY

The coefficient of x^2*y^3*z in the polynomial expansion of (2x - y^2 + 3z)^6 can be determined using the multinomial theorem. This theorem allows for the calculation of coefficients in polynomial expansions without the need for full multiplication. The specific coefficients involved are 2, -1, and 3, which represent the terms in the polynomial. The discussion emphasizes the efficiency of using combinatorial methods over direct multiplication.

What is the coeffcient of x^2*y^3*z in the polynomial(2x-y^2+3z)^6?
please give me an example, and how do i deal with coeffienct that is inside the function 2, -1, and 3.

You could always do it the long way...and multiply it all out and see what the coefficient is...but I imagine you're asking is there an easier way right?
 
The coefficient x^2*y^3*z is really easy. Are you sure you didn't mean x^2*y^6*z ?
