Question

(iv)
a² + b - ab- a factorise

Answer 1

Answer:

take X as a and y as b

${x}^{2} - x - xy + y \\ x(x - 1) - y(x - 1) \\( x - y)(x - 1)$

Answer 2

Answer:

Your question is a² + b - ab -a OK

Step-by-step explanation:

Step - I : first, bring this polynomial in standard form means their term degree wise.

i.e a² - ab + b - a

Step - II : then, take common from a² - ab and b - a

i.e a(a-b) + 1 ( a-b)

step - III : put them in separate Bracket

i.e ( a +1 ) ( a - b)

So, ( a + 1 ) ( a - b) is a factors of

a² + b - ab - a
