x2 – xz + xy – yz=? A. (x – z) (x + z) B. (x – y) (x – z)�

1.	x2 – xz + xy – yz=? A. (x – z) (x + z) B. (x – y) (x – z) C. (x + y) (x – z) D. (x – z) (z – x)
Answer» = x² – xz + xy – yz = x(x – z) +y(x – z) (taking x and y as common resp.) = (x + y)(x – z).

x2 – xz + xy – yz=? A. (x – z) (x + z) B. (x – y) (x – z) C. (x + y) (x – z) D. (x – z) (z – x)

Answer»

= x² – xz + xy – yz

= x(x – z) +y(x – z) (taking x and y as common resp.)

= (x + y)(x – z).
