Answer 1

hey dear
here is ur answer
...
9x^4+y^2+z^2+6x^2 y-2yz-6x^2 z
=(3x^2)^2+y^2+z^2+2(3x^2)(y)+2 (y)(-z)+2 (3x^2)(-z)
=(3x^2+y-z)^2
=(3x^2+y-z)(3x^2+y-z)

hope this will help you :)

Answer 2

$({3x} {}^{2} )^{2} + (y) {}^{2} + ( - z) {}^{2} + 2( {3x}^{2})(y) + 2(y)( - z) + 2( {3x}^{2})( - 2) \\ = ( {3x}^{2} + y - z) {}^{2} \\ = ( {3x}^{2} + y - z)( {3x}^{2} + y - z)$
using formula:-(x+y+z)²=x²+y²+z²+2xy+2yz+2zx
