Question

factorise X square + Z square - 2 x z​

Answer 1

Answer:

(x-z)²

Step-by-step explanation:

$> > {(x - z)}^{2} = {x}^{2} + {z}^{2} - 2xz < < \\ = {(x -z) }^{2}$

Answer 2

Answer:

Step-by-step explanation:

x^2 + z^2 - 2xz

It is a formula of (a - b)^2

So it will be,

(x - z)^2

OR

(x - z) (x - z)
