Melody is factoring the expression 13 - 2:2 + 41 – 8. Her first two steps are shown. 3 - 2x2 + 4x - 8 = x2(x - 2) + 4(x - 2) (x + 4)(x - 2) What should Melody do next to finish factoring the expression? OA. Melody should rewrite (x^2 + 4) as (x - 2) (x + 2).

O B. Melody has completely factored the expression.

Oc. Melody should rewrite (x^2 + 4) as (x+ 2)^2.

OD. Melody should rewrite (x^2 + 4) as (x - 2)^2.
