Expanding the expression using the distributive property:

= (2x-3)(x+1)(3-x)
= (2x-3)(x+1)(-x+3)
= (2x)(x)(-x) + (2x)(x)(3) + (2x)(1)(-x) + (2x)(1)(3) + (-3)(x)(-x) + (-3)(x)(3) + (-3)(1)(-x) + (-3)(1)(3)
= -2x^3 + 6x^2 - 2x^2 + 6x + 3x^2 - 9x - 3x + 9
= -2x^3 + 7x^2 - 6x + 9

Therefore, (2x-3)(x+1)(3-x) simplifies to -2x^3 + 7x^2 - 6x + 9.
