Question

expand by using identity (2x+3y-4z)^2​

Answer 1

Answer:

a² + b² + c² + 2(ab - ac - bc) or a² + b² + c² + 2ab - 2ac - 2bc

Step-by-step explanation:

Answer 2

Answer:

4x² + 9y² + 16z + 12xy - 24yz - 16zx this is ur expand form

Step-by-step explanation:

(2x+3y-4z)²

(a+b-c) = a² + b² + c² + 2(ab - bc - ca)

(2x+3y-4z)² = (2x)² + (3y)² + (4z)² + 2[(2x) (3y) - (3y)

(4z) - (4z) (2x)

(2x+3y-4z)² = 4x² + 9y² + 16z + 12xy - 24yz - 16zx
