Q3 of 105 Page 279

Workout the following divisions:

12x (8x – 20) ÷ 4(2x – 5)

In the given term


Dividend = 12x (8x – 20)


Take out the common part in binomial term


= 2 × 2 × 3 × x(2 × 2 × 2 × x - 2 × 2 × 5 )


= 2 × 2 × 2 × 2 × 3 × x(2 × x - 5 )


= 48x (2x - 5 )


Divisor = 4(2x – 5)



= 12x


Hence divides 12x (8x – 20) by 4(2x – 5) gives out 12x
