How to factor a third degree polynomial
Web1 de nov. de 2024 · How to: Factor a third-degree polynomial, given one of its factors. Use synthetic division to divide the polynomial by \((x−k)\). Confirm that the remainder is \(0\). Write the polynomial as the product of \((x−k)\) and the quadratic quotient. If possible, factor the quadratic and write the polynomial as the product of three linear factors. WebUse 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. And that is the solution: x = −1/2. (You can also see …

WebSorted by: 11. By the Rational Zero Theorem all the rational roots of x3 − 12x + 9 must have a numerator which is a factor of 9 and a denominator which is a factor of 1. Therefore they have to be of the form 9 1 = 9 or 3 1 = 3. Let f(x) = x3 − 12x + 9. Since f(9) = 630 and f(3) = 0, 3 is a root of f(x). So it can be factored as. WebOn this page we learn how to factor polynomials with 3 terms (degree 2), 4 terms (degree 3) and 5 terms (degree 4). We'll make use of the Remainder and Factor Theorems to …
WebIf we know one linear factor of a higher degree polynomial, we can use polynomial division to find other factors of the polynomial. For example, we can use the fact that (x+6) is a factor of (x³+9x²-108) in order to completely factor the polynomial. We just need to be careful because the polynomial has no x-term.
