Use the Rational Zero Theorem to list all possible rational zeros of the function. How do you know if a quadratic equation has two solutions? A vital implication of the Fundamental Theorem of Algebra, as we stated above, is that a polynomial function of degree n will have \(n\) zeros in the set of complex numbers, if we allow for multiplicities. The zeros are \(4\), \(\frac{1}{2}\), and \(1\). Now we have to divide polynomial with $ \color{red}{x - \text{ROOT}} $. Recall that the Division Algorithm states that, given a polynomial dividend \(f(x)\) and a non-zero polynomial divisor \(d(x)\) where the degree of \(d(x)\) is less than or equal to the degree of \(f(x)\),there exist unique polynomials \(q(x)\) and \(r(x)\) such that, If the divisor, \(d(x)\), is \(xk\), this takes the form, is linear, the remainder will be a constant, \(r\). From the source of Wikipedia: Zero of a function, Polynomial roots, Fundamental theorem of algebra, Zero set. Similarly, if \(xk\) is a factor of \(f(x)\), then the remainder of the Division Algorithm \(f(x)=(xk)q(x)+r\) is \(0\). Our online calculator, based on Wolfram Alpha system is able to find zeros of almost any, even very complicated function. Real numbers are a subset of complex numbers, but not the other way around.
