MCQ
The factorisation of $x^2 + xy + 2x + 2y$ is:
- ✓$(x + 2)(x + y)$
- B$(x + 2)(x y)$
- C$(x - 2)(x + y)$
- D$(x - 2)(x - y)$
✓
Answer
Correct option: A.
$(x + 2)(x + y)$
A. $(x + 2)(x + y)$
Solution:
$= x^2 + xy + 2x + 2y$
$= x(x + y) + 2(x + y)$
$= (x + 2) (x + y)$
Solution:
$= x^2 + xy + 2x + 2y$
$= x(x + y) + 2(x + y)$
$= (x + 2) (x + y)$
