\begin{lgathered}{9x}^{2} - 30x + 25 = 0 \\ {9x}^{2} - (15 + 15)x + 25 = 0 \\ {9x}^{2} - 15x - 15x + 25 = 0 \\ 3x(3x - 5) - 5(3x - 5) = 0 \\ (3x - 5)(3x - 5) = 0 \\ \\ 3x - 5 = 0 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3x - 5 = 0 \\ \: \: \: \: \: \: \: \: 3x = 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3x = 5 \\ \: \: \: \: \: \: \: \: \: \: x = \frac{5}{3} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{5}{3}\end{lgathered}
