Question

Vistaar Karo ( x - 2 y - 3 z ) Square​

Answer 1

$\tt \red{(x−2y−3z)^2}$

$\tt \green{=(x+−2y+−3z)(x+−2y+−3z)}$

=(x)(x)+(x)(−2y)+(x)(−3z)+(−2y)(x)+(−2y)(−2y)+(−2y)(−3z)+(−3z)(x)+(−3z)(−2y)+(−3z)(−3z)

$\small \tt \pink{=x^2−2xy−3xz−2xy+4y^2+6yz−3xz+6yz+9z^2}$

$\color{blue} \tt=x^2−4xy−6xz+4y^2+12yz+9z^2$

Answer 2

Answer:

answer is x²+4y²+9z²-4xy+12yz-6xz
