Question

factorise= x square + z square - 2xz​

Answer 1

Answer:

=a2-2ab+b2

=(X)2-2(x)(y) +(z)2

=(X-z)2

HOPE IT HELPS.

Answer 2

Answer:

${a}^{2} + {b}^{2} - 2ab = {(a - b)}^{2}$

Here, a = x and b = z

$\: \: \: \: {x}^{2} + {z}^{2} - 2 xz$

$= {x}^{2} + {z}^{2} - 2 \times x \times z$

$= {(x - z)}^{2}$
