Answer 2

Answer:

Please correct the question as:

Factorize 4x²+9y²+16z²+12xy-24yz-16xz

Step-by-step explanation:

4x²+9y²+16z²+12xy-24yz-16xz

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

Now Let 2x=a,3y=b and -4z=c

then this expression becomes as:

a²+b²+c²+2ab+2bc+2ca=(a+b+c)²

Returning values of a,b and c we get

Hence the answer=(2x+3y-4z)²
