Math, asked by namku, 1 year ago

in transformation of roots i got that the roots need to be reduced by -1 to get an equation without the second term how do i find the new equation ?

namku: then for x^4 term will i have to exapnd (x-1)^4 ?

rational: why do you want to expand? did they ask you to expand and write in standard polynomial form ?

namku: they gave in expanded form :)

rational: oh they gave the options in standard form is it

namku: yes

rational: then you're right, i guess we need to expand (x-1)^4

namku: ok thanks a lot ur awesome !

rational: np:) you want to learn synthetic division?

namku: was just abt to post that q. gimme 2 sec

namku: In the last few minutes, fill out all the unattended questions with some random option, preferably a or c for obvious reasons. - read this somewhere in tips for exams but couldnt figure out what are the obviuose reasons ? have any idea ?

To reduce the roots of f(x) by $k$ , simply replace $x$ by $x+k$ . That is, the roots of $f(x+k)$ will be $k$ less than the roots of $f(x)$
