Answer 2

$\sf{\pmb{ANSWER:}}$

$(2x + 3)^{2} = 25 \\ \\ 4 {x}^{2} + 2(2x)(3) + {3}^{2} = 25 \\ \\ 4 {x}^{2} + 12x + 9 = 25 \\ \\ 4 {x}^{2} + 12x = 25 - 9 \\ \\ 4 {x}^{2} + 12x = 16 \\ \\ 4 {x}^{2} + 12x - 16 \div 2 \\ \\ {x}^{2} + 3x - 4 \\ \\ {x}^{2} + 4x - 1x - 4 \\ \\ x(x + 4) - 1(x + 4) \\ \\ (x - 1) (x + 4) \\ \\ \: \: \: \: \: \: x = 1x = - 4$
