Answer» x² + 6x + 8 Factorizing the equation and taking x and 2 as common, = x² + 4x + 2x + 8 = x(x + 4) +2(x + 4) = (x + 2)(x + 4).

x2 + 6x + 8=? A. (x + 3) (x + 5) B. x + 3) (x + 4) C. (x + 2) (x + 4) D. (x + 1) (x + 8)

Answer»

x² + 6x + 8

Factorizing the equation and taking x and 2 as common,

= x² + 4x + 2x + 8

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

= (x + 2)(x + 4).
