Answer 2

Hope u like my process
=====================
$25x(x + 1) = - 4 \\ \\ or. \: \: 25x + 25 {x}^{2} = - 4 \\ \\ or. \: \: 25 {x}^{2} + 25x + 4 = 0 \\ \\ or. \: \: 25 {x}^{2} + 20x + 5x + 4 = 0 \\ \\ or. \: \: 5x(5x + 4) + 1(5x + 4) = 0 \\ \\ or. \: \: (5x + 1)(5x + 4) = 0 \\ \\ so..either \: \: x \: = - \frac{1}{5} \\ \\ or..x = - \frac{4}{5}$
Hope this is ur required answer
