anonymous · Answer

do you mean f(x)=4x+194?

anonymous · Answer

and  when the f(x)=0?

anonymous · Answer

no, thats the problem f(x)= x^4+25x^2+144

anonymous · Answer

oh, ok  i got it
sorry my compu's got some probs , i'll try to come back later, 
hope sb can help caro for now

anonymous · Answer

Caroo - is there a chance that the middle term is 24x^2 instead of 25x^2?

harsimran_hs4 · Answer

well this seems biquadratic equation but you can rewrite it as y^2 + 25y + 144 = 0 
where x^2 = y
and solve it just as quadratic equation........i hope you know the formula for this...

dumbcow · Answer

Factor
16+9 = 25
16*9 = 144

--> (x^2 +16)(x^2 +9) = 0

x^2 +16 = 0    --> x = +-4i
x^2 +9 = 0     --> x = +-3i
