@jigglypuff314 are you available? :P
I only just finally understood polynomial division myself recently so I'm not sure if I can explain it that well .-. I can try tho :3 look at the highest power of the thing you are dividing by and compare it to the highest power of the thing you are dividing into so in this case we are comparing 3x^2 and x does that make sense so far? :)
lol I think so.
ok so now I have to think what should we multiply to "x" to make it "3x^2" ?
that would be 3x right? because x * 3x = 3x^2 ? so we multiply through 3x times (x + 6) and get 3x^2 - 18x
Yes it be 3x. why do we multiply?
You just recently understood this so nvm my questions lol
x times (something) = 3x^2 because of how division works, 3x^2 divided by this (something) = x the values we found would make our division look like this |dw:1450150424583:dw|
I'm horrible at division. Do I only substract now?
yep ^_^ try subtracting 3x^2 + 25x -(3x^2 + 18x) -------------------
6x^2 +43x ? If i understand this substraction too then its a blue moon victory.
minusssingggg we are attempting to make the 3x^2 in the big stuff disappearrr
3x^2 - 3x^2 = 0 great now 25x - 18x = ?
perfect! so now we have |dw:1450151226378:dw|
now what do we have to multiply to x in order to get 7x ?
7 :D lol
YAY so (x+6) * 7 = ? (distributive property)
great! now note that the minus is also distributive :) |dw:1450151491074:dw|
perfect! so your remainder would be -1 and your quotient would be 3x + 7
omg this was such a mental workout for me but now i can catch up on my division skills ! Do you have time for a few more problems c: or no
half an hour :3
yay ok lets make so math magic...
