Question

Factorise 30n² - 87n + 30
can someone help pls quickly
thanks ​

Answer 1

`3(5n - 2) * (2n - 5)`

Explanation:

`30 {n}^(2) - 87n + 30`

`3(10 {n}^(2) - 29n + 10)`

`3(10 {n}^(2) - 4n - 25n + 10)`

`3(10 {n}^(2) * (5n - 2) - 25n + 10)`

`3(2n * (5n - 2) - 5(5n - 2))`

`= 3(5n - 2) * (2n - 5)`

Answer 2

it is 3(5n-2)x(2n-5)
