Answer:

B po

Step-by-step explanation:

yan yung sagot ko basta yan yun

Answer:

b.) 2

Step-by-step explanation:

(x - __ ) (x2 + 2x + 4) = x3 - 8

say the missing term is 2,

[tex](x-2) (x^{2} + 2x +4 )[/tex]

multiplying & simplifying, the result should be [tex]x^{3} - 8[/tex]

[tex]x^{3} + 2x^{2} + 4x - 2x^{2} - 4x - 8[/tex]    (rearranging)

[tex]x^{3} + 2x^{2} - 2x^{2} + 4x - 4x - 8[/tex]

[tex]x^{3} - 8[/tex], therefore the missing term is 2.
