How to Identify Zeros of Binomials? Let us first determine what root or a zero of a polynomial is. The root of the polynomial means that by solving a function, you will get a non-zero answer. This value is called the root of a function. However, if by solving a function, your answer is 0, then that means you get no value for solving it. Now, a binomial function means that in a given equation, two unknowns are present. Now, we will find out how we can identify a zero in a binomial equation. Let us take an example of y=x^2+2x-15. First, we need to solve the equation to find out its roots. Let us consider y as zero for solving this problem. x^2+2x-15=0, x^2+5x-3x-15=0, (x+5)(x-3)=0 Now, if we write the last equation separately, then, we get (x+5)=0, (x-3)=0 Both separate equations can be solved as roots, so by placing the constants from the left-hand side of the equal sign to the right-hand-side, the signs will change. The resultant values will be x=3, x=-5 If we look at it objectively, the binomial equation had two zeros and two roots. Similarly, we can solve other binomial equations as well. These worksheets and lessons help students locate and understand how to find a root of a polynomial. These are values of x or y that cause the polynomial to equal zero.
