Calculadora de ceros

Encuentra los ceros de una función paso a paso

La calculadora intentará encontrar los ceros (exactos y numéricos, reales y complejos) de la función de valor lineal, cuadrático, cúbico, cuártico, polinomial, racional, irracional, exponencial, logarítmico, trigonométrico, hiperbólico y absoluto en el intervalo dado.

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 write it in the comments below.

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

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

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