Question

please answer the question with explanation

Answer 1

option b is correct i think so

Answer 2

COMPARE THE GIVEN EQUATION WITH THE IDENTITY A^{2} - B^{2} = ( A+B)(A-B)

LET X^2 BE A AND (X-Z)^2 BE B

SOLVING IT , U GET ,

(X^2+(X-Z)^2)(X^2-(X-Z)^2)

AGAIN ,Y THE SECOND BRACKET HAS THE SAME IDENTITY ,.

SO IT BECOMES ,

(X^2+(X-Z)^2)(X+(X-Z)(X-(X-Z))

SOLVING IT ,

(2X^2-2ZX+Z^2)(Z(2X-Z)

HENCE OPTION C IS CORRECT .

HOPE I EXPLAINED IT RIGHTLY .
