Calculadora de Zeros

Encontre os zeros de uma função passo a passo

A calculadora tentará encontrar os zeros (exatos e numéricos, reais e complexos) da função linear, quadrática, cúbica, quártica, polinomial, racional, irracional, exponencial, logarítmica, trigonométrica, hiperbólica e de valor absoluto no 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

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

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