let P(x) = x³ – 4x² – 7x + 10. Because there is no GCF and no difference or sum of cubes, you must use other information to factor the polynomial. Once you find out that P(c) = 0, you know (x – c) is a factor of P(x) based on the Factor Theorem of algebra. ...
This follows directly from the fact that at an extremum, the derivative of the function is zero. If a polynomial is ofndegrees, its derivative has n – 1 degrees. For example, take the 2nd degree polynomial 3x2. The derivative (using thepower rule) is the first degree polynomial, 6x. T...
3x^3+ 8x^2- 9x + 2 is an example. You can't use grouping to factor out a GCF in a way that would produce a common factor. In order to explain how this works, you need to know that when solving an equation by factoring, you need to set the factored out thing equal to 0 and...
Making a Polynomial Function with Irrational Zeroes: If we need to make a polynomial function, with one independent variable, with Irrational Zeroes, we can do it choosing a second-degree polynomial with irrational roots. Answer and Explanation:1 There exist infinite forms to make a polynomial wi...
What is a Power Function? A power function has the form where: a and p are constants, p is a real number, and a is nonzero. We call a the scaling factor, and p is the exponent or the power. The polynomial functions we work with in much of algebra are simply combinations of pow...
Locate the x-intercepts, if possible. If you can, factor your polynomial function. (If it doesn't factor, it most likely means your x-intercepts are not integers.) For the given example, the function factors to: f(x) = (x+1)(x-2)(x-4). In this form, you can see if any of...
Factoring by grouping is one way to factor a polynomial. This tutorial shows you how to take a polynomial and factor it into the product of two binomials. Then, check your answer by FOILing the binomials back together! Keywords: problem expression polynomial factor ...

Set the factors equal to zero. x - 4 = 0 and x2- 2x + 2 = 0 x = 4 To solve for x from the other factor, use the quadratic formula: x = (-b ±√(b2- 4ac)) / 2a where: a = 1 b = -2 c = 2 Plug in these values into the quadratic formula. Because we are using ...
댓글:kadash 122017년 11월 3일 Is there a function that allows me to directly get the of exponential value of polynomial. Example: P=x^6-x^4+3x^2+1 and coefficient P(2) exponent [6 4 2 1] and 4 Thanks for the help. ...
