Question

Simplify (15x^2 - 24x +9) / (3x - 3)

Answer 1

Use ac grouping here.
(15x^2-15x-9x-9)/(3x-3)
(15x(x-1)-9(x-1))/(3x-3)
(15x-9)(x-1)/(3(x-1))
3(5x-3)(x-1)/(3(x-1))
5x-3

Answer 2

thanks

Answer 3

In the first line I meant to put -9x+9 so it should look like this:
Use ac grouping here.
(15x^2-15x-9x+9)/(3x-3)
(15x(x-1)-9(x-1))/(3x-3)
(15x-9)(x-1)/(3(x-1))
3(5x-3)(x-1)/(3(x-1))
5x-3
