Question

Expand each of the following using suitable identity (x+2y+4z)²

Answer 1

Hello friends!!

Here is your answer :

${(x + 2y + 4z)}^{2}$


Using identity :

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


${(x)}^{2} + {(2y)}^{2} + {(4z)}^{2} + 2(x)(2y) + 2(2y)(4z) + 2(4z)(x)$



${x}^{2} + {4y}^{2} + {16z}^{2} + 4xy + 16yz + 8zx$



Hope it helps you...
