y=\left(-\frac{1}{2}x^{2}+\frac{1}{2}\right)\left(x-2\right)\left(x+1\right)
Use the distributive property to multiply -\frac{1}{2} by x^{2}-1.
y=\left(-\frac{1}{2}x^{3}+x^{2}+\frac{1}{2}x-1\right)\left(x+1\right)
Use the distributive property to multiply -\frac{1}{2}x^{2}+\frac{1}{2} by x-2.
y=-\frac{1}{2}x^{4}+\frac{1}{2}x^{3}+\frac{3}{2}x^{2}-\frac{1}{2}x-1
Use the distributive property to multiply -\frac{1}{2}x^{3}+x^{2}+\frac{1}{2}x-1 by x+1 and combine like terms.
