Question

Factori 3x2 + 27y2 + z2 - 18xy + 6 √3yz -2 √3zx

Answer 1

3x² + 27y² + z² - 18xy + 6 √3yz -2 √3zx

⇒ [-√3 x+3√3y+z]²

Answer 2

Answer:

The identity here is (a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca

Step-by-step explanation:

therefore (-$\sqrt{3}$x)^2+(3$\sqrt{3}$y)^2+z^2+2(-$\sqrt{3}$x)(3$\sqrt{3}$y)+2(3$\sqrt{3}$y)(z)+2(z)(-$\sqrt{3}$x)

=(-$\sqrt{3}$x+3$\sqrt{3}$y+z)^2
