When noting the "c" term, you should look at the sign of the term, whether it is positive or negative. This "c" term happens to be When multiplying the two final terms of the two binomials, consider how you could possibly end up with The only way to end up with a negative when multiplying is by multiplying a positive number and a negative number. Therefore, the two numbers in our binomial are opposite signs. The only way to multiply to get a 1 is by having a 1 multiplied by 1. Therefore we know the two terms in these binomials have to be -1 and 1. Now consider the first term in the quadratic. However this is not correct!!!! Then, the middle terms would cancel out. So we conclude that it is not possible to factor this quadratic. The only way to solve it is by the quadratic equation, and if you did so you would have complex roots. We can be sure this is the case because the final "c" term has no other factors than -1 and 1, however, when we put this into our binomial it doesn't factor correctly. In other words, this binomial is prime.

Wolfram Alpha is a great tool for factoring, expanding or simplifying polynomials. It also multiplies, divides and finds the greatest common divisors of pairs of polynomials; determines values of polynomial roots; plots polynomials; finds partial fraction decompositions; and more. Enter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask about factoring. Get immediate feedback and guidance with step-by-step solutions and Wolfram Problem Generator. A polynomial with rational coefficients can sometimes be written as a product of lower-degree polynomials that also have rational coefficients. In such cases, the polynomial is said to "factor over the rationals.
