plz bata do urgent hai​

Answer 1

Answer:

-8xy+8xz

Step-by-step explanation:

STEP 1- 1ST SIMPLIFY (2X-Y+Z)^2

THEN WE GAIN 4x^2-4xy+4xz+y^2-2yz+z^2

STEP 2- THEN SIMPLIFY -(2x+y-z)^2

THEN WE GAIN 4x^2+4xy-4x^2+y^2-2yz+z^2

NOW JOIN RESULTS OF STEP 1 AND STEP 2

THEN IT BECOMES 8x(-y+z)

= -8xy+8xz
