Question

factorise 2x square + 5 y square + Z square minus 2 square root 10 x y - 2 square root 5 y z + 2 square root 2 z x​

Answer 1

Answer:

Step-by-step explanation:

-√2x)^2 + (y)^2 + (2√2z)^2 + 2(-√2)(1)xy + 2(1)(2√2)yz + 2(2√2)(-√2)xz

This is in the form of a^2+b^2+c^2 +2ab + 2bc + 2ca = (a+b+c)^2

Here a= -√2x         b=y      c=2√2

So it is simplified as

Ans. (-√2x+y+2√2z)^2
