The factors of \bf 4x^2+y^2+z^2-4xy-2yz+4zx are \bf \red{(2x-y+z)(2x-y+z)}

Given:

4x^2+y^2+z^2-4xy-2yz+4zx\\

To find:

Factors of given polynomial.

Solution:

Identity used:

\bf (a+b+c)^2=a^2+b^2+b^2+2ab+2bc+2ac\\

Step 1:

Write the given polynomial in terms of standard identity.

(2x)^2+(-y)^2+z^2+2(2x)(-y)+2(-y)z+2(2x)z\\

Step 2:

Compare the given polynomial with standard identity.

 a^2=4x^2

Thus,

a=2x

2ab= -4xy

Thus,

b=-y

 c^2=z^2

Thus,

c=z

Step 3:

Identity which can be written is (2x-y+z)^2

Thus,

Factors of given polynomial are \bf (2x-y+z)(2x-y+z).
