Question

Factorise : 25x2+y2+9z2-10xy-6yz+30xz​

Answer 1

$\bf\huge\textbf{\underline{\underline{According\:to\:the\:Question}}}$  

= 25x^2 + y^2 + 9z^2 - 10xy - 6yz + 30xz

= (5x)^2 + (-y)^2 + (3z)^2 + 2 (5x)(-y) + 2(-y)(3z) + 2(5x)(3z)

= [(5x) + (-y) + 3z]^2

= (5x - y + 3z)^2

Answer 2

25x^2+y^2+9z^2-10xy-6yz+30xz

=(25x^2+y^2+9z^2)^2

=(25x^2+y^2+9z^2)(25x^2+y^2+9z^2)
