Polynomials are also an essential tool in describing and predicting traffic patterns so appropriate traffic control measures, such as traffic lights, can be implemented. It must show measurements, degrees, angles and curves, and curves are expressed using polynomials. A polynomial is a special type of mathematical expression. The coefficient of a term is the non-variable factor of that term. Note that each term can be positive or negative, and this sign depends on whether the term was added in the polynomial or subtracted in the polynomial. Summing the cost of items on a grocery bill can be interpreted as a polynomial. Notice there is no need to write (x - root1)(x - root2) = 0. \[\begin{array}{ccccc} When determining the rate at which the account has increased, the account owner is calculating the slope of the line that shows the changes in the accounts balance. There are two polynomials: \((2x^3+x^2+x+1)\) and \((2x^2+3x+4)\). Expertise from Forbes Councils members, operated under license.
