\frac{3844}{25}-\frac{372}{5}x+9x^{2}+\left(\frac{9}{5}\right)^{2}
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(\frac{62}{5}-3x\right)^{2}.
\frac{3844}{25}-\frac{372}{5}x+9x^{2}+\frac{81}{25}
Calculate \frac{9}{5} to the power of 2 and get \frac{81}{25}.
157-\frac{372}{5}x+9x^{2}
Add \frac{3844}{25} and \frac{81}{25} to get 157.
