HOW TO SOLVE FOR B AND C

gusty zealot Sep 14, 2024, 4:07 PM

#

i got it but working out is long

#

z=-2+root(2)i,z=-2-root(2)i,z=2+3i,z=2-3i

#

just multiply out and compare coefficinets

#

wait theres probably better solution

gusty zealot Sep 14, 2024, 4:54 PM

#

yh i did that

#

its long but it works

#

you dont have to actually multiply out

#

you can kinda skip it in a way

gusty zealot Sep 14, 2024, 4:55 PM

#

i did it to find the values of a,b,c

#

and then i just used quadratic formula on the ax^2+bx+c to get the other roots

#

anyway the main problem i came across is the fact that this guy used a and b in his quadratic
