Solve -a^2-3/2+a^2

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

Evaluate

$$\frac{a^{2}-3}{2}$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply a^{2} times \frac{2}{2}.

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

Since \frac{-a^{2}-3}{2} and \frac{2a^{2}}{2} have the same denominator, add them by adding their numerators.

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

Combine like terms in -a^{2}-3+2a^{2}.

$$\frac{a^{2}-3}{2}$$

Expand
