Question

URGENT!! WILL MAKE YOU BRAINEST

FACTORISE:

4x²+y²+z²-4xy-2yz+4xy​

Answer 1

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)

Answer 2

Answer:

2x+y+z

Step-by-step explanation:

(a+b-c)^2

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

=2x+y+z
