[1] We learned that a Quadratic Function is a special type of polynomial with degree 2; these have either a cup-up or cup-down shape, depending on whether the leading term (one with the biggest exponent) is positive or negative, respectively. The power of the largest term is your answer! wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. Asking you to find the zeroes of a polynomial function, y equals (polynomial), means the same thing as asking you to find the solutions to a polynomial equation, (polynomial) equals (zero). Notation and terminology. Polynomial Roots Calculator. Step 2 . Factoring 5th degree polynomials is really something of an art. When we encounter such a problem, then either the polynomial is of a special form which allows us to factor it, or we must approximate the solutions with a graphing utility. Exercise 5. The answer is 2 since the first term is squared. The degree is the same as the highest exponent appearing in the final product, so you just multiply the two factors and you'll wind up with x³ as one of the terms in the product. In the case of a polynomial with only one variable (such as 2x³ + 5x² - 4x +3, where x is the only variable),the degree is the same as the highest exponent appearing in the polynomial (in this case 3).
