Answer 1

$\huge\bold\red\star\underline\blue{AnSwer:}$

${x}^{2} + 6x + 8 = 0 \\ \\ = > {x}^{2} + 2x + 4x + 8 = 0 \\ \\ = > x(x + 2) + 4(x + 2) = 0 \\ \\ = > (x + 2)(x + 4) = 0 \\ \\ = > x = - 2 \: (or) \: x = - 4$

Answer 2

x²+6x+8

x²+(4+2)x+8

x²+4x+2x+8

x(x+4)+2(x+4)

(x+4)(x+2)

x = -4 and x = -2
