Factoring Quadratic Trinomials: Leading Coefficents of 1
To factor a quadratic trinomial you must find factors of C which the sum is B. When C is positive, the factors must have the same sign. When C is negative, the factors must have different signs. When factoring a quadratic trinomial use the quadratic equation to solve it the easy way or you could also use the box method.

Ex: Factoring when C is Positive x^2+3x+2=(x+2) (x+1) Ex:The factors of 6 that add up to 5 are 2 and 3. x^2+5x+6=(x+2) (x+3) Ex: The factor of 8 that adds up to 9 is 8 and 1. x^2+9x+8=(x+8) (x+1) PRACTICE PROBLEM #1 FACTOR: a^2-4a+3  PRACTICE PROBLEM #2 FACTOR: X^2+9X+14
