Question 2
Algebraic ExpressionsFactorise: x + y − ax − ay
- A.(x − y)(1 − a)
- B.(x + y)(1 + a)
- C.(x + y)(1 − a)
- D.(x − y)(1 + a)
Show the answer and explanation
Answer: C ((x + y)(1 − a))
Explanation
x(1 − a) + y(1 − a) = (x + y)(1 − a).
Factorise: x + y − ax − ay
Answer: C ((x + y)(1 − a))
x(1 − a) + y(1 − a) = (x + y)(1 − a).
