Polynomials may be quadratic or having any degree of x. The polynomial which has two terms is called the binomial. Polynomials which have three or more terms are known as the polynomials. The quadratic equations can be solved by breaking the middle terms and by making the perfect squares. The online calculators or the tools are used to solve the complicated equations quickly and efficiently. The modern online calculators have only one window for the input and the output. The expressions for which the factors are to be found are entered into the input window. Let us take one example of factoring.

x² – y² = ( x + y ) ( x –y) , by plugging the value of x and y

150² - 50² = (150 + 50) (150 – 50), to add and subtract 50 from 150 is very easy. We get 200 and 100. The multiplication of the two factors is twenty thousand as shown below.

= 200 X 100 = 20000
