I WILL MARK YOU AS BRILLIANT IF YOU ANSWER THIS QUESTION 8.factorise x 2 +9y 2+36z 2+ 6xy + 36yz+12xz

Answer 1

Answer:

$we \: know \: that \: {a + b + c}^{2} = {a}^{2} + {b}^{2} + {c}^{2} + 2ab + 2bc + 2ca$

${x}^{2} + {9y}^{2} + {36z}^{2} + 6xy + 36yz + 12xz = \\ {(x)}^{2} + {(3y)}^{2} + {6z)}^{2} + 2 \times x \times 3y + 2 \times 3y \times 6z + 2 \times x \times 6z \\ = {(x + 3y + 6z)}^{2} \\ (x + 3y + 6z)(x+3y+6z)$

I hope it will help you.
