Question

Plzz answer the following question very fast

Answer 1

It is of the form a²+b²+c²+2ab+2bc+2ca=(a+b+c)²

Since 2ab is of the form 2√2xy, a is negative.

a=√2x

b=y

c=√8z=2√2z

Therefore after factorisation we get

(-√2x+y+2√2z)²

Hope it helps..

Answer 2

Answer:

Step-by-step explanation:

The question is to factorize this:

=> 2x²+y²+8z²-2√2xy + 4√2yz - 8xz

=> (√2x)²+(-y)²+(2√2z)² -2√2xy + 4√2yz - 8xz

=> ( √2x - y - 2√2z)²

According to the formula (a+b+c)²=

a²+b²+c²+ 2ab + 2bc + 2ac.
