Question

Evaluate:- (X - 2y— 3z)²

Answer 1

Hey there!

Evaluate:- (x - 2y- 3z)


Expression in the form of identity
(x + y + z)² = x² + y² + z² + 2xy + 2yz + 2zx

Where,

x = x
y = -2y
z = -3z

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

= x² + 4y² + 9z² + (-4xy) + (-12yz) + (-6zx)

Hope helped.
