1.	Expand the following by using suitable identities (x+2y+4z)hole square
Answer» ONG>Step-by-step EXPLANATION: (x+2Y+4z) using identity., (a+b+c )² =a²+b²+c²+2ab + 2BC + 2CA here , a= x , b= 2y and c = 4z ( x+ 2y+ 4z ) ² =x² + (2y )²+ (4z) ²² + ( 2×x× 2y) + ( 2×2y × 4z ) + ( 2×4z ×x ) = x² + 4y² + 16z² + 4xy + 16 yz + 8xz

Answer» ONG>Step-by-step EXPLANATION:

(x+2Y+4z)

using identity.,

(a+b+c )² =a²+b²+c²+2ab + 2BC + 2CA

here , a= x , b= 2y and c = 4z

( x+ 2y+ 4z ) ²

=x² + (2y )²+

(4z) ²² + ( 2×x× 2y) + ( 2×2y × 4z ) + ( 2×4z ×x )

= x² +

4y² + 16z² + 4xy + 16 yz + 8xz
