\frac{5\left(V+3\right)}{75}+\frac{3\left(v^{2}+3v\right)}{75}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 15 and 25 is 75. Multiply \frac{V+3}{15} times \frac{5}{5}. Multiply \frac{v^{2}+3v}{25} times \frac{3}{3}.
\frac{5\left(V+3\right)+3\left(v^{2}+3v\right)}{75}
Since \frac{5\left(V+3\right)}{75} and \frac{3\left(v^{2}+3v\right)}{75} have the same denominator, add them by adding their numerators.
\frac{5V+15+3v^{2}+9v}{75}
Do the multiplications in 5\left(V+3\right)+3\left(v^{2}+3v\right).
