Question

4x²+y²+z²-4xy-2yz+4xz factorise​

Answer 1

Answer:

(-2x + y - z) ^2

Step-by-step explanation:

= question

acorrding to formula of (a+b+c)^2

= {(-2x )+ (y)+ (-x)}^2

= (-2x + y - z) ^2 answer

I hope it is useful for you.

Answer 2

Step-by-step explanation:

4x*x + y*y + z*z - 4xy - 2yz + 4xz

= (2x)(2x) + (-y)(-y) + z*z + 2(2x)(-y) + 2(-y)(z) + 2(2x)(z)

= (2x-y+z)(2x-y+z)
