16000=400x/(x^2+100)
We move all terms to the left:
16000-(400x/(x^2+100))=0
Domain of the equation: (x^2+100))!=0We multiply all the terms by the denominator
x∈R
-(400x+16000*(x^2+100))=0
We calculate terms in parentheses: -(400x+16000*(x^2+100)), so:We get rid of parentheses
400x+16000*(x^2+100)
We multiply parentheses
16000x^2+400x+1600000
Back to the equation:
-(16000x^2+400x+1600000)
-16000x^2-400x-1600000=0
a = -16000; b = -400; c = -1600000;
Δ = b2-4ac
Δ = -4002-4·(-16000)·(-1600000)
Δ = -102399840000
Delta is less than zero, so there is no solution for the equation
