Question

How do you find all zeros by factoring

Answer 1

Set the function equal to 0.Using "educated guessing", find two integers whose product equals c and whose sum equals b. These integers are always factors of c.Form a product of factors containing the variable and each of the integers found.Set each factor equal to 0 and solve to find the Zeros.
