This online calculator finds the roots of given polynomial. Find an nth degree polynomial function satisfying the given conditions. A polynomial has #alpha# as a zero if and only if #(x-alpha)# is a factor of the polynomial. So your 4th degree polynomial will have zeros of -1, 2, 1-2i and 1+2i. There are three given zeros of -2-3i, 5, 5. The calculator will find 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. A polynomial of real coefficients will have as many zeros as the degree of the polynomial. Able to display the work process and the detailed explanation. Since 5 and 2i are roots (zeros), we know that x-5 and x-2i are factors. Suppose that a polynomial function of degree 5 with rational coefficients has 0 (with multiplicity 2), 3, and 1 –2i as zeros. Also, any complex zeros will come in conjugate pairs. If we want a polynomial with real coeficients, then the complex conjugate of 2i (which is -2i) must also be a root and x+2i must be a factor. Example: Find all the zeros or roots of the given function. DEGREE: 3 Why does the graph of this polynomial have one x intercept only? The calculator will show you the work and detailed explanation.
