 {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}
