WebDec 17, 2024 · They are obviously -3 and -3. Since a and c are the same, the two quadratic factors are the same. This means that the given polynomial is indeed a SQUARE: x^4 - 6x^3 + 11x^2 - 6x + 1 = (x^2 - 3x + 1)^2 Its roots are therefore those of x^2 - 3x + 1 = 0 Now, by the quadratic formula, we get: x = (3 +/- Sqrt 5)/2. WebSolution: According to the given information, the cost of the notebook can be expressed as (2x + 4) Answer: Therefore on factoring polynomials, the factors of (2x + 4) are 2 and (x + …
Web4. Roots of a Polynomial Equation. Here are three important theorems relating to the roots of a polynomial equation: (a) A polynomial of n-th degree can be factored into n linear factors. (b) A polynomial equation of degree n has exactly n roots. (c) If `(x − r)` is a factor of a polynomial, then `x = r` is a root of the associated polynomial equation.. Let's look at … WebOct 6, 2024 · We can see that there is a root at x = 2. This means that the polynomial will have a factor of ( x − 2). We can use Synthetic Division to find any other factors. Because x = 2 is a root, we should get a zero remainder: So, now we know that 2 x 3 − 3 x 2 + 2 x − 8 = ( …
