Question

factorise x^2+4y^2+9z^2+4xy+12yz+6zx​

Answer 1

Answer:

identity used - (x +y+z) ^2

hence, the answer will be - (x + 2y+ 3z) ^2

Step-by-step explanation:

hope you have a great day ahead

Answer 2

Answer:

$\sf(x +2y + 3z)^2$

Step-by-step explanation:

$\sf{x}^2 + {4y}^2 + {9z}^2 +4xy+12yz+16zx$

$\sf{(x)}^2 + {(2y)}^2 + {(3z)}^2 + 2 (2xy) + 2(2y×3z) +2(3z×x)$

$\sf(x +2y + 3z)^2$
