student : In class we're working on dividing polynomials using long division, synthetic division, etc. My friend and I were thrown off by these two problems though...
student : Given that two of the roots of x^4-2x^2-3x-2=0 are -1 and 2, solve the equation for x.
student : And...
student : Oh okay
student : thank you
tutorpm : x^4-2x^2-3x-2=0 , or, x^4=2x^+3x+2 , or, (x-2)(x+1)(x^2+x+1)=0, so, when (x-2)=0 , or, x=2. and when (x+1)=0 , or, x=-1.
student : Oh wow, thank you so much! We have a quiz tomorrow and this really helps. The other one is "Given that one root of x^4-4x^3+6x^2-16x+8=0 is 2i, solve the equation for x" It's the same concept, but the imaginary number confuses us
tutorpm : Please note, due to lack of resources, we can only do 1 problem FREE in 24 hours period. You can always come back tomorrow for another free problem. Please, tell your friends about our free service - 1 free in 24 hours
tutor2 : Get 1 homework problem done for 99 cents only. [PUSH]https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=XESLHRSKH5HKJ[/PUSH]
student : Oh okay, that's fine. I will, and thanks for your help!
tutorpm : welcome
