How to: Given a polynomial function \(f(x)\), use the Rational Zero Theorem to find rational zeros. Notice that two of the factors of the constant term, 6, are the two numerators from the original rational roots: 2 and 3. Some examples of a linear polynomial function are f(x) = x + 3, f(x) = 25x + 4, and f(y) = 8y 3. See, Allowing for multiplicities, a polynomial function will have the same number of factors as its degree. if we plug in $ \color{blue}{x = 2} $ into the equation we get, $$ 2 \cdot \color{blue}{2}^3 - 4 \cdot \color{blue}{2}^2 - 3 \cdot \color{blue}{2} + 6 = 2 \cdot 8 - 4 \cdot 4 - 6 - 6 = 0$$, So, $ \color{blue}{x = 2} $ is the root of the equation. a = b 10 n.. We said that the number b should be between 1 and 10.This means that, for example, 1.36 10 or 9.81 10 are in standard form, but 13.1 10 isn't because 13.1 is bigger The calculator computes exact solutions for quadratic, cubic, and quartic equations. The three most common polynomials we usually encounter are monomials, binomials, and trinomials. The polynomial can be up to fifth degree, so have five zeros at maximum. Use the Factor Theorem to find the zeros of \(f(x)=x^3+4x^24x16\) given that \((x2)\) is a factor of the polynomial.

The polynomial can be written as, The quadratic is a perfect square. The process of finding polynomial roots depends on its degree. In a multi-variable polynomial, the degree of a polynomial is the sum of the powers of the polynomial. Use synthetic division to divide the polynomial by \((xk)\). Write the polynomial as the product of factors. However, when dealing with the addition and subtraction of polynomials, one needs to pair up like terms and then add them up. 4x2 y2 = (2x)2 y2 Now we can apply above formula with a = 2x and b = y (2x)2 y2 If the remainder is 0, the candidate is a zero. Polynomial Form Because \(x =i\) is a zero, by the Complex Conjugate Theorem \(x =i\) is also a zero. The Rational Zero Theorem tells us that if \(\dfrac{p}{q}\) is a zero of \(f(x)\), then \(p\) is a factor of 1 and \(q\) is a factor of 4. The constant term is 4; the factors of 4 are \(p=1,2,4\). \[ \begin{align*} 2x+1=0 \\[4pt] x &=\dfrac{1}{2} \end{align*}\].
