Question

Factorise:
2 1. x² + z² - 2xz​

Answer 1

Answer:

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

using formula,

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

so answer will be ,

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

HOPE IT HELPS

Answer 2

AnswEr :

➡ x² + z² - 2xz

▣ (a - b)² = a² + b² - 2ab

➡ (x)² + (z)² - 2 × x × z

➡ (x - z)²
