So, each part of a polynomial in an equation is a term. Either task may be referred to as "solving the polynomial". Do NOT count any constants("constant" is just a fancy math word for 'number'). Answer. You don't have to do this on paper, though it might help the first time. If you want to find the degree of a polynomial in a variety of situations, just follow these steps. You're really going to have to sit and look for patterns. The exponent of the first term is 2. One common special case is where there is no constant term. In the case of a polynomial with more than one variable, the degree is found by looking at each monomial within the polynomial, adding together all the exponents within a monomial, and choosing the largest sum of exponents. You can find oblique asymptotes using polynomial division, where the quotient is the equation of the oblique asymptote. It is very unlikely that you would have a square matrix of a higher degree in math problems, because, according to the Abel–Ruffini theorem, a general polynomial equation of degree five or higher has no solution in radicals, thus, it can be solved only by numerical methods. Remember ignore those coefficients. For Polynomials of degree less than 5, the exact value of the roots are returned. The first degree polynomial equation = + is a line with slope a. A polynomial of degree 2 is known as a quadratic polynomial. Etymology. Welcome to MathPortal.
