HEYA..........✌✌✌✌

HERE IS YOUR ANSWER...........

________________________________

9x^2+4y^2+16z^2+12xy-16yz-24xz
==>>(3x)^2+(2x)^2+(4z)^2+{2(3x)(2y)}-{2(2y)(4z} -{2(4z)(3x)
We know that
(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca
It is of that form only and in this sum we see the subtraction in y at xy and yz. So y only has subraction symbol

===>>[2x-3y+4z]^2
