ab - b = ab - 1b = b(a-1)
i really need to go back and understand factoring again. i never understand when you can do it and when you cant
ive been doing this for another 10 hours straight today so my brain is refusing to comprehend anything you guys are saying
you can always do it when theres a common factor inside multiple terms being added or subtracted
in this case that common factor is (2/3)^x
yeah u need to understand factoring at a gut level its pretty fundamental
start with the distributive property of multiplication a(b+c) = ab + ac
then look at it backwards
then look at that structure over a thousand problems until you do it automatically
whenever you see
ab+ac
you gotta feel the perverse desire to pull out the a
a(b+c)
First define the real numbers and their order
the distributed version is lame anyway if ur gonna post a solution most of the time the factored version is more friendly
i can understand without thinking factoring out xs out of a 5th 6th 7th or whatever degree polynomial but i cant do it when its more basic i dont understand
like i can find the GCF of 40 different degree binomials literally without thinking but ive always been shit at this and im upset
asoul leave the fucking thread you ape
its prolly cuz u drilled on too specific of a application. u really gotta nail down the general case a(b+c) = ab+ac.
i think its a failure of secondary education cuz they teach you how to factor in the specific case but don't properly drill it in ur head the generality. if u do competitive math it becomes second nature
hmm yes it is not my fault
okay we are going to break this down really slowly so my dumb brain will understand
Both of these terms are A, YES?
im literally drawing blank on how to do this
i would suggest taking a break at this point, perhaps getting some exercise or rest

is THAT the correct step
both A turn into 1?
