Expand (x+y+z)^2 formula
Expand (x+y+z)^2 formula-⇒ (2 x − y z) 2 = (2 x) 2 (− y) 2 (z) 2 2 (2 x × − y) 2 (− y × z) 2 (z × 2 x) = 4 x 2 y 2 z 2 − 4 x y − 2 y z 4 x z Was this answer helpful? (2x y z)² = {2x ( y) z}² = (2x)² ( y)² (z)² {2 × 2x × ( y)} (2 × 2x × z) {2 × ( y) × z} = 4x² y² z² 4xy 4xz 2yz, which is the required expansion #
