Question

9 X square + 16 y square + 4 z square - 24 X Y + 16 Y Z - 12 x z

Answer 1

Answer:

(3x-4y-2z)^2

Step-by-step explanation:

9x^2+16y^2+4z^2-24xy+16yz-12xz

BY USING IDENTITY,

(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca

where, a=(3x) , b=(-4y) and c=(-2z)

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

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

[3x+(-4y)+(-2z)]^2

[3x-4y-2z]^2

Answer 2

Step-by-step explanation:
