Question

14 factories:4x2+9y2 +16z2+12xy-2xyz-16zx​

Answer 1

Answer:

(2x+3y-4z)²

Step-by-step explanation:

2²+9y²+16z²+12xy-24y-16xz

=(2x)²+(3y)²+(4z)²+12xy-24yz_16xz

=(2x)²+(3y)²+(-4z)²+12xy-24yz-16xz

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

using (a+b+c)² formula

putting a =2x b=3y c=-4z

this will helps you well
