Question

factorise= 9x²+4y²+16z²+12xy-16yz-24xz​

Answer 1

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

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

So using this identity it can be fractorised.

Answer 2

Answer

Hi buddy  hope this will be helpful to you

Step-by-step explanation:

9x2+4y2+16z2+12xy-16yz-24xz

16z(z+y)+12x(z+y)+32x2+22y2

(16z+12x)(z+y)+32x2+22Y2
