Answer:
4x^3-6x^2-6x+9
Explanation:
I would write out the solutions as expressions and expand them:
(x-2)(x-1/2)(x-3/2)
(x^2-1/2x-2x+1)(x-3/2)
(x^2-5/2x+1)(x-3/2)
x^3-(3/2)x^2-(5/2)x+15/4+x-3/2
x^3-(3/2)x^2-(3/2)x+9/4
Next, since the leading coefficient has to be 4x^3, I could just multiply the entire expression by 4:
4x^3-(12/2)x^2-(12/2)x+36/4
4x^3-6x^2-6x+9
Hopefully, this was helpful! Comment below if you would like me to explain further!
