MCQ
The factorisation of $36x^2y^2 - 1$ is:
- ✓$(6xy - 1) (6xy + 1)$
- B$(6xy - 1)^2$
- C$(6xy + 1)^2$
- D$(6 + xy)^2$
✓
Answer
Correct option: A.
$(6xy - 1) (6xy + 1)$
A. $(6xy - 1) (6xy + 1)$
Solution:
$= 36x^2y^2 - 1 = (6xy)^2 - (1)^2$
$= (6xy - 1) (6xy + 1)$
Solution:
$= 36x^2y^2 - 1 = (6xy)^2 - (1)^2$
$= (6xy - 1) (6xy + 1)$
