Solving A Polynomial Equation Given Roots Youtube When solving an equation given roots, the original equation can be reduced to a depressed equation using synthetic division. the roots of this depressed equ. Solving polynomials given a root. use synthetic division to find the extra roots to a polynomial equations.
Polynomial Equations Given The Roots Youtube This precalculus video tutorial provides a basic introduction into solving polynomial equations. it explains how to solve polynomial equations by factoring. We may be able to solve using basic algebra: example: 2x 1. 2x 1 is a linear polynomial: the graph of y = 2x 1 is a straight line. it is linear so there is one root. use algebra to solve: a "root" is when y is zero: 2x 1 = 0. subtract 1 from both sides: 2x = −1. divide both sides by 2: x = −1 2. Step 1: check for common factors. if the terms have common factors, then factor out the greatest common factor (gcf). step 2: determine the number of terms in the polynomial. factor four term polynomials by grouping. factor trinomials (3 terms) using “trial and error” or the ac method. A quadratic equation has roots 𝛼 and β. given that and 𝛼 2 β 2 = 12, find two possible quadratic equations that satisfy these values (both of which have 1 as the leading coefficient). the quadratic equation 3x 2 2x – 4 = 0 has roots 𝛼 and β. find the values of s 1, s 2 and s 1. you are given the quadratic equation 4x 2 – x.

If you’re solving an equation, you can throw away any common constant factor. (technically, you’re dividing left and right sides by that constant factor.) but if you’re factoring a polynomial, you must keep the common factor. example: to solve 8 x ² 16 x 8 = 0, you can divide left and right by the common factor 8. Correct answer: x = 4, x = −3. explanation: the polynomial in the problem is given as follows: x2 − x − 12 = 0. factoring this polynomial, we would get an expression of the form: (x − a)(x − b) = 0. so we need to determine what a and b are. we know we need two factors that when multiplied equal 12, and when added equal 1.
