 2 {y}^{2} - 34y - 76  = 0\\ 2 {y}^{2} - 38y  + 4y  - 76 = 0 \\ 2y(y - 19) + 4(y - 19) = 0 \\ (y - 19)(2y + 4) = 0 \\ y - 19 = 0 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: 2y + 4 = 0 \\ y = 19 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: 2y =  - 4 \\ y = 19 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: y =   \frac{ - 4}{2} \\ y = 19 \:  \:  \:  \:  \: or \:  \:  \:  \:  \: y =  - 2
