Question
Factorise:
4(a + b) - 6(a + b)2
4(a + b) - 6(a + b)2
✓
Answer
4(a + b) - 6(a + b)2
= (a + b)[4 - 6(a + b)]
= 2(a + b)(2 - 3a - 3b)
= 2(a + b)(2 - 3a - 3b)
= (a + b)[4 - 6(a + b)]
= 2(a + b)(2 - 3a - 3b)
= 2(a + b)(2 - 3a - 3b)

Arun is participating in an 8 miles walk. The organizers used a square coordinate grid to plot the course. The starting point is at A (3, 1). At B (3, 4), there's a water station to make sure the walkers stay hydrated. From water station, the walkway turns right and at C (6,4) a garden is situated to keep walkers fresh. From the garden, the walkway turns left and finally, Arun reaches at destination D to complete 8 miles.
