i think the answer is A am i correct? Factor completely: 8m3 − 12m2 + 4m A 2m (4m2 − 6m + 2) B 4 (2m3 − 3m2 + m) C 4m (2m − 1)(m − 1) D 4m (2m2 − 3m)
you can actually pull out a 4m
IF this is the answer --> A 2m (4m2 − 6m + 2), ask yourself if (4m2 − 6m + 2) will factor. It is possible that the expression is only partially factored. @shinebrightlikeadimon
well yes because you can simplify 6 even more so now i think it's d
not d i mean b
well looking at b did they pull out 4m or just 4?
so it's d since they did pull out m correct?
If we pull out a 4m from the whole equation it would look like this \[4m(2m^2-3m+1) \] What do you think? Is it completely factored?
yes
D is not the correct option. It does not multiply back to the original question. @shinebrightlikeadimon
actually you can break it down even more
ok so you can break down the ^2?
so it's not A, B, or D so it's c
close yes \[2m^2-3m+1\] we know m time m equals m^2 so (2m+ ?)(m+?) we can then look at our 1 and we know the only way to get one it so multiply 1 times 1 (2m+1)(m+1) but we need a - 3 in the middle so our equations need negatives to be -3x so we get (2m-1)(m-1) solve it out and 2m^2-2m-1m+1 = 2m^2 -3m+1 our original equation and the final answer is \[4m(2m-1)(m-1) \]
Yes your answer is C
