WitrynaThe rational root theorem, or zero root theorem, is a technique allowing us to state all of the possible rational roots, or zeros, of a polynomial function. We learn the theorem and see how it can be used to find a polynomial's zeros. Tutorials, examples and exercises that can be downloaded are used to illustrate this theorem.

If there exists a k E [1, n - 1] such that a 2 < aklak+1, then f(x) has imaginary roots.

WitrynaWe recall the conjugate root theorem, which states that the complex roots of a quadratic equation with real coefficients occur in complex conjugate pairs. Furthermore, since a quadratic equation only has two roots, 𝑐 + 𝑑 𝑖 must be the conjugate of 𝑎 + 𝑏 𝑖. Hence, 𝑐 + 𝑑 𝑖 = (𝑎 + 𝑏 𝑖) = 𝑎 − 𝑏 𝑖.

Witrynax2 − 9 has a degree of 2 (the largest exponent of x is 2), so there are 2 roots. Let us solve it. A root is where it is equal to zero: x2 − 9 = 0. Add 9 to both sides: x2 = +9. Then take the square root of both sides: x = ±3. So the roots are −3 and +3. population of slaughters kyWitrynaExample 1.
