Question

Factorise 15(2x-3)³-10(2x-3)

Answer 1

Step-by-step explanation:

taking 5(2x-3) common,

5(2x-3)(3(2x-3)²-2)=

5(2x-3)(3(4x²+9-12x)-2)

=5(2x-3)(12x²+27-36x-2)

=5(2x-3)(12x²-36x+25).

it is not further factorizable to integer coeff. but you can find roots to the quadratic factor I got.
