Best ResponseYou've already chosen the best response.3yup, so those are your zeros x = 3, x = 11, x = 8

Best ResponseYou've already chosen the best response.0Factor the GCF: −6m2 + 18m − 36. −6(m2 − 3m + 6) −1(6m2 − 18m + 36) −6m(m2 − 3m + 6) −6(m2 + 3m − 6) can u just give the answer then explain for both im in the middle of a lesson and its about to end lol :))

Best ResponseYou've already chosen the best response.3hint: the greatest common factor is 6, so we divide each term by 6 and write 6 outside

Best ResponseYou've already chosen the best response.3we can also factor out 1, which reverses each of the signs inside the parentheses

Best ResponseYou've already chosen the best response.0so witch one are you on? im leaning towards c

Vocaloid

Best ResponseYou've already chosen the best response.3it's not c you can't factor out m since not every term has m in it (36 doesn't have m)

Vocaloid

Best ResponseYou've already chosen the best response.3like I said before... the GCF is 6 which goes on the outside of the parentheses... then we reverse the signs

Best ResponseYou've already chosen the best response.3multiply each of the answer choices out to see which one matches the original hint: (AB)(C+D) = A*C + A*D  B*C  B*D

Vocaloid
 one year ago
Best ResponseYou've already chosen the best response.3so, using our first answer choice as an example... (AB)(C+D) = A*C + A*D  B*C  B*D (3x − 4)(x + 2) = (3x)(x) + 2(3x)  4*x  8 = 3x^2 + 2x  8 which does NOT match the original so we keep going
