Work out the following divisions.
(i) `(10x - 25) -: 5`
(ii) `(10x - 25) -: (2x - 5)`
(iii) `10y(6y + 21) -: 5(2y + 7)`
(iv) `96abc(3a -12)(5b - 30) -: 144(a - 4)(b - 6)`

Text Solution

Verified by Experts

Here is the solution:
(i) `(10x - 25) ÷ 5`
Factorising, (10x - 25) , we get
`(10x - 25) = 5× 2 × x - 5 × 5`
