Factoring polynomials having three terms of the form ax 2 + bx + c To factor polynomials having three terms of the form ax 2 + bx + c, (1) check to see whether you can monomial factor (factor out common terms). Then if a = 1 (that is, the first term is simply x 2 ), use double parentheses and factor the first term. Place these factors in the left sides of the parentheses. For example, ( x )( x ) (2) Factor the last term and place the factors in the right sides of the parentheses. To decide on the signs of the numbers, do the following. If the sign of the last term is negative, (1) find two numbers (one will be a positive number and the other a negative number) whose product is
