Answer:

x = -4,-2

Step-by-step explanation:

x² + 6x + 8 = 0

Factor the equation

(x+4)(x+2) =0

Using the zero product property

x+4 =0   x+2 =0

x=-4  x=-2

x = -4,-2

Answer:

[tex] \sf \: x = - 2 \: \: or \: \: - 4[/tex]

Step-by-step explanation:

[tex] \sf {x}^{2} + 6x + 8 = 0[/tex]

Factorise.

[tex] \sf {x}^{2} + 6x + 8 = 0 \\ \sf {x}^{2} + 4x + 2x + 8 = 0[/tex]

[tex] \sf x(x + 4) + 2(x + 4) = 0 \\ \sf(x + 2)(x + 4) = 0[/tex]

Use the zero product property.

[tex] \sf \: x + 2 = 0 \\ \sf \: x = 0 - 2 \\ \sf x = - 2[/tex]

Or

[tex] \sf \: x +4 = 0 \\ \sf \: x = 0 - 4 \\ \sf \: x = - 4[/tex]

Therefore,

[tex] \sf \: x = - 2 \: or \: \: - 4[/tex]
