(2x-1)(x+3)(x-5).
2x³-5x²-28x+15
Write 5x² and -28 as a difference.
=2x³-x²-4x²+2x-30+15
Then factor out x², -2x and +15 from the expression.
=x²(2x-1) - (2x (2x+1) -15 (2x+1)
Factor out 2x+1 .
=(2x-1) x (x²-2x-15)
Write -2x as a difference.
=(2x-1) (x²+3x-5x-15)
Factor out x and -5 from the expression.
=(2x-1) x(x+3) -5 (x+3)
And lastly, factor out x+3 from the expression.
=(2x-1)(x+3)(x-5)
