1. Box Method for Factoring Factoring expressions in the form of

2. Factor the x-box way Middle b= Sum Product ac m n First and Last Coefficients y = ax 2 + bx + c Last term 1st Term Factor n Factor m Base 1Base 2 GCF Height

3. Box Method for Factoring We are going to factor the expression First draw a box and divide into quarters.

4. Box Method for Factoring Now we are going to place the terms of the expression into the box. Look at the expression: Place the in the top left box. Place the -2 in the bottom right box. -2

5. Box Method for Factoring Make your X and find two numbers that multiply to -30. -2

6. Box Method for Factoring Now we are going to list the factors of -30. -30 -1 30-30*1 -2 152*-15 -3 103*-10 -5 65*-6 Are there any pair of numbers that would equal -7?

7. Box Method for Factoring We just found the factors of -30 that have a sum of -7! We will place those factors in the box with an “x” It doesn’t matter which box you put them in. -2 -10x 3x

8. Box Method for Factoring Now we are going to pull out the common factors from each row and column. Last sign out of the box determines the sign. -2 +3x -10x +1 5x 3x-2

9. Box Method for Factoring We now have the factors of The factors are: (5x + 1)(3x - 2)  The answer is: (5x + 1)(3x - 2)=
