Question

Factorise

x-1-(x-1)^2+ax-a
​

Answer 1

Answer:

Step-by-step explanation:

x -1 - (x - 1)² + ax - a,

(x - 1) - (x - 1)² + ax - a,

(x - 1) {1 - (x - 1)} + a (x - 1),

(x - 1) {1 - (x - 1)} + a,

(x - 1) {1 -x +1} + a,

(x - 1)×x + a,

x² - x + a.

So the factor of given question is x² - x + a.
