Question

`m) xz-yz-x^2+2xy-y^2 `

ptđttnt

Answer 1

\(xz-yz-x^2+2xy-y^2\)

\(=z\left(x-y\right)-\left(x-y\right)^2\)

\(=\left(x-y\right)\left(z-x+y\right)\)

Answer 2

m)xz−yz−x2+2xy−y2

\(=z.\left(x-y\right)-\left(x^2-2xy+y^2\right)\)
 

= \(z.\left(x-y\right)-\left(x-y\right)^2\)

= (x-y).(z-x+y)
