Answer 2

$\large \bold \green{answer} \\ \\ \implies \bold{x = - 1} \\ \\ \implies \bold{x = - 5} \\ \\ \implies \bold \blue{ \underline{explanation}} \\ \\ \implies \bold{(x + 5) {}^{2} - 4(x + 5) } \\ \\ \implies \bold{ {x}^{2} + 25 + 10x - 4x - 20 = 0 } \\ \\ \implies \bold{ {x}^{2} + 6x + 5 = 0 } \\ \\ \implies \bold{x {}^{2} + 5x + x + 5 = 0 } \\ \\ \implies \bold{x(x + 5) + 1(x + 5) = 0} \\ \\ \implies \bold{(x + 1)(x + 5) = 0} \\ \\ \implies \bold \therefore{x = - 1 \: \: \:and \: \: \: \: x = - 5}$
