Question

$(x {}^{2} - 2xy + y {}^{2} ) - x {}^{2}$
factorise​

Answer 1

(x^2 - 2xy + y^2) - x^2
=(x - y)^2 - x^2

Answer 2

Answer:

(x² - 2xy + y^2) – z²

Answer:

x^2 - y^2 -z^2

Step-by-step explanation:

(x^2 - y^2) = x^2 - 2xy -y^2

So,( x^2 - 2xy -y^2) - z^2

=(x^2 - y^2) - z^2

=x^2 - y^2 - z^2
