We can use polynomial equations to describe real-life situations. Finding the roots (x-intercepts) and turning points (peaks and valleys) to these equations yields important and meaningful information. In the case of business or physics situations, the results might indicate at what time an object will hit the number of solutions of polynomial equations, the nature of these solutions (be they real or complex, rational or irrational), and techniques for ﬁnding the solutions. We call values of x that satisfy equation (2) roots or solutions of the equation. They are also called zeros of the polynomial Pn(x). When n = 1, equation (2) is called a linear ... Finding Real Roots of Polynomial Equations Identify the roots of each equation. State the multiplicity of each root. Example 2B: Identifying Multiplicity x4+ 8x3+ 18x2–27 = (x–1)(x+ 3)(x+ 3)(x+ 3) x –1 is a factor once, andx + 3 is a factor three times. The root 1 has a multiplicity of 1. The root –3 has a multiplicity of 3. x4+ 8x3+ 18x2–27 = 0 Name Answer hea. LESSON Practice B. 6-5 Finding Real Roots of Polynomial Equations. Solve each polynomial equation by factoring. 1. 9x3 -- 3x2 – 3x + 1 = 0.

factoring a polynomial equation is one way to find its real roots. Recall the Zero Product Property. You can find the roots, or solutions, of the polynomial equation P(x) = 0 by setting each factor equal to 0 and solving for x. Example 1 – Using Factoring to Solve Polynomial Equations .
