Kalkulator Titik Nol

Temukan akar-akar fungsi langkah demi langkah

Kalkulator akan mencoba menemukan akar-akar (eksak dan numerik, real dan kompleks) dari fungsi linear, kuadrat, kubik, kuartik, polinomial, rasional, irasional, eksponensial, logaritmik, trigonometri, hiperbolik, serta fungsi nilai mutlak pada interval yang diberikan.

Enter an equation:
Like x^2+3x+4=0 or sin(x)=x.
Find the solution with respect to:
Enter an interval: ,
Leave empty, if you don't have any restrictions.
Only real roots will be searched for if you specify the interval, regardless of whether the box is checked.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Your input: solve the equation $$$x^{4} - 16 x^{3} + 90 x^{2} - 224 x + 245=0$$$ for $$$x$$$ on the interval $$$\left( -\infty,\infty \right )$$$

Answer

Real roots

$$$x=5$$$

$$$x=7$$$

Complex roots

$$$x=2 + \sqrt{3} i\approx 2.0 + 1.73205080756888 i$$$

$$$x=2 - \sqrt{3} i\approx 2.0 - 1.73205080756888 i$$$
