Best ResponseYou've already chosen the best response.1LHS = (4d4)(3d2) = (4d)(3d) + (4d)(2) + (4)(3d) + (4)(2) = 12d^2 – 8d – 12d +8 = 12d^2 – 20d + 8  (1) But RHS = 12d^2 + _d + 8 (2) Therefore from (1) and (2), Missing Coefficient is 20.

Best ResponseYou've already chosen the best response.0yes, so expand and simplify the lefthandside it'd end up in a quadratic, and you'd see the middle term :)

Best ResponseYou've already chosen the best response.1that's what i think the expression has 3 terms a leading term with a power of 3 is a cubic
