Answer:

4n² + 9y² + 16z² + 12ny - 24yz - 16zn

Step-by-step explanation:

Using (a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca

(2n+3y-4z)^2 =2n^2+3y^2+(-4z)+2(2n+

=> (2n)² + (3y)² + ( - 4z)² + 2[ (2n)*(3y) + (3y)*(- 4z) + (- 4z)*(2n)]

=> 4n² + 9y² + 16z² + 2(6ny - 12yz - 8zn)

=> 4n² + 9y² + 16z² + 12ny - 24yz - 16zn
