Zeros Calculator
The calculator will try to find the zeros (exact and numerical, real and complex) of the linear, quadratic, cubic, quartic, polynomial, rational, irrational, exponential, logarithmic, trigonometric, hyperbolic, and absolute value function on the given interval.
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
$$$x=2 + \sqrt{3} i\approx 2.0 + 1.73205080756888 i$$$
$$$x=2 - \sqrt{3} i\approx 2.0 - 1.73205080756888 i$$$
