Solve =-1/2*3(n^2-n+2)

$$= - \frac { 1 } { 2 } \cdot 3 ( n ^ { 2 } - n + 2 )$$

Evaluate

$$\frac{3\left(-n^{2}+n-2\right)}{2}$$

Solution Steps

Multiply -\frac{1}{2} and 3 to get -\frac{3}{2}.

$$-\frac{3}{2}\left(n^{2}-n+2\right)$$

Use the distributive property to multiply -\frac{3}{2} by n^{2}-n+2.

$$-\frac{3}{2}n^{2}+\frac{3}{2}n-3$$

Expand

$$-\frac{3n^{2}}{2}+\frac{3n}{2}-3$$

Solution Steps

Multiply -\frac{1}{2} and 3 to get -\frac{3}{2}.

$$-\frac{3}{2}\left(n^{2}-n+2\right)$$

Use the distributive property to multiply -\frac{3}{2} by n^{2}-n+2.

$$-\frac{3}{2}n^{2}+\frac{3}{2}n-3$$
