Question

Expand this
(2x+3y+4z)²​

Answer 1

Step-by-step explanation:

(2x+3y+4z)²

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

=4x²+9y²+16z²+12xy+24yz+16xz

Answer 2

Answer: (2x + 3y + 4z)² =

Here we can use the ( a + b +c)² = a² + b² + c² + 2ab + 2bc + 2ca

Here we have (2x + 3y + 4z)² so :

(2x)² +  (3y)² + (4z)² + 2(2x)(3y) + 2(3y)(4z) + 2(4z)(2x)

4x² + 9y² + 16z² + 12xy + 24yz + 16zx
