A. [tex]12x^3 + 28x^2 + 21x + 30[/tex]
B. [tex]12x^3 - 28x^2 - 21x + 30[/tex]
C. [tex]12x^3 + 28x^2 - 21x + 30[/tex]
D. [tex]12x^3 - 28x^2 - 21x - 30[/tex]

Answer :

Answer:

12x3 - 28x2 - 21x + 30

terms in x^2 are -10x^2 - 18x^2 = -28x^2 so the answer is either b or d.

the number at the end is -5 * -6 = + 30

so the answer must be b
