\frac{3\left(2p^{2}+3p\right)}{6a}-\frac{5p\times 2a}{6a}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2a and 3 is 6a. Multiply \frac{2p^{2}+3p}{2a} times \frac{3}{3}. Multiply \frac{5p}{3} times \frac{2a}{2a}.
\frac{3\left(2p^{2}+3p\right)-5p\times 2a}{6a}
Since \frac{3\left(2p^{2}+3p\right)}{6a} and \frac{5p\times 2a}{6a} have the same denominator, subtract them by subtracting their numerators.
\frac{6p^{2}+9p-10pa}{6a}
Do the multiplications in 3\left(2p^{2}+3p\right)-5p\times 2a.
