Zeroes of a function

The zero of a function is a number that can plugged in fr x in f(x) to solve the equation. There are two methods of finding the zeros - long division and synthetic division. Although the synthetic division is easier, it only applied to linear equations. For quadratics, the long division but be used. They long division is essentially the same as any long division problem except that there are variables dividing and being divided as well. Synthetics division is when you plug in the given zero and then write out the coefficients die each term and then multiply each product of each term by the divisor until you reach the last which is the remainder. The answer may be written as f(x)=d(x)q(x)+r(x). D stands for divisor, q for quotient, and r for remainder.
