resno, no! proooosim...me zanima, ce se kaj znam od matematike izpred 15 ih let.

Sicer ne vem, kdo je (bil) Brecht, ampak zna bit', da bom res koga likvidirala s katero od teh knjig.

hvala!

Aaa, to je pa celo meni vsaj za prebrat' bolj logično. Čakaj malo... grem prepisat enačbo, pa da vidim, kaj bom spackala iz nje.

kako ze gre?
a na kvadrat + 2ab + b na kvadrat ?

a je prou? mi je se kaj ostalo v tej blond buči?

A potem bi bilo tole (za začetek)...

a x (a-4)2 - (a-3)3 - a x (42-26a) = ???

pa da ti še 1x ponovim mojo ponudbo: na posodo imam: vsa Branja, vse 'na pragu besedila', tempus (mat za 4. letnik), Kosovo književnost (šenkam); ostalo sm na žalost že pošenkala/prodala.

Še čas za kofe najdeva, Felicita, pa se bova vse zmenili.

Hmmm... a x a = a2, a ne?

A x -4 =  -4a?

A x 42 = 42a?

A x -62a = ???

a na kubik tut (še) znaš? pa vietovo pravilo?


in preden se komu začne iz glave kadit, rešitev je 27*(a-1)^2

(a + b)* = a* + 3a#b + 3ab# + b* 

legenda:
na kubik = *
na kvadrat = #

a2 - a3 + 17a?

kaj je pa ze to?

ce je naki na neki, pol pomeni da je neki na neki neki.... ane?

res je... haklc naprej, kaj gre najprej in kaj gre skupi

vietovo pravilo: vidiš ena, dva, tri člene in si rečeš - vieeeeeetovo pravilo približno tkole: x^2 + 4x - 21 = (x-3)(x+7)

pazis, da ne zmesas jaboljk pa hrusk, pa da je deljenje/ mnozenje pred + in -....

točno to, paziš na vrstni red operacij, predznake, kvadrate in kube, na koncu bi mogla dobit ax^3 + bx^2 + cx + d - če se seveda kej ne pokrajša (in tukej se), potem ko dobiš tako obliko pa krajšaša itd.

šit, sej res ja... to je bla pa una piflarija, ko mi je sla na zivce!
btw kerensa, men se zdi, da ni pravilno. tko, od oka

Obožujem strokovno ocenjevanje.

nope, rezultat je 27(a-1)^2

evo, ker se mi glih da, jest bi, na moj počasen način po korakih šla tkole:

a(a-4)^2 - (a-3)^3 - a(43-26a) =

a (a^2 - 8a + 16) - (a^3 - 9a + 27a - 27) - 43a + 26a^2 (znebila sm se kvadratnih in kubičnih členov, zadnji člen pomnožila)

a^3 - 8a^2 + 16a - a^2 + 9a - 27a + 27 - 43 a + 26a^2 (pomnožila 1. člen in se znebila minusov)

zdej pa seštejem jabolka, hruške, grozdje itd in dobim: 27a^2 - 54a + 27

izpostavim 27: 27* (a^2 - 2a + 1)

zadnji člen vidim da je kvadrat, okrajšam do konca: 27* (a-1)^2

Saj to pa res ni toliko: 55 zgodb si boš pa ja zapomnila: zgodba, liki, avtor, kdaj je bilo napisano pa itak po stilu precej spoznaš, pa eni so itak tako znani, da že zdaj veš... ma, 55 knjig tudi ni tak problem prebrat do spomladi - 1 na teden, če bi imela čisto celo leto na voljo. Ne vem, kako je, če se to kampanijsko učiš, mi smo to jemali pač celo srednjo šolo. Pa sem na koncu vedela zakaj se je šlo tudi za tiste iz 1. letnika - saj to si zapomniš, to so knjige, to ni ena piflarija .

Face ste s to matematiko . Ste mi kar lušte nardile .
