Question

How to factorise with suitable identity X square + Z square - 2 x z

Answer 1

Answer:

x²+z²-2xz is in the form of a²+b²-2ab

a²-2ab+b² = (a-b) ²

So x²+z²-2xz = (x-z) ²

Answer 2

$\boxed{\huge{\mathtt{\underline{\red{Answer:-}}}}}$

This is how you can factories it:-

${x}^{2} + {y}^{2} -2xy \\ = {(x)}^{2} + {(y)}^{2} - 2.x.y \\ = {(x - y)}^{2} (ans)$

HOPE IT IS HELPFUL.
