Answer 1

x square +2x +3x
x square +3x- x square+ 3x
x(x+3)- x(x+3)
(x+3) (x-x)

Answer 2

${x}^{2} + 2x + 3 = 0 \\ \\ = > {x}^{2} + (3 - 1)x + 3 = 0 \\ \\ = > {x}^{2} + 3x - x + 3 = 0 \\ \\ = > x(x + 3) - 1(x + 3) = 0 \\ \\ = > (x + 3)(x - 1) = 0 \\ \\ \\ \\ \\ x + 3 = 0 \\ \\ = > x = - 3 \\ \\ \\ \\ x - 1 = 0 \\ \\ = > x = 1$
