- 1. How to Factor ax 2 + bx + c Pick an example problem to use, and delete the others: 12x 2 + 23x + 5
- 2. 12x 2 + 23x + 5 Step 1. First you are suppose to organize all of your numbers into A, B, and C like this: 12x 2 +23x +5 a b c
- 3. Step 2: Then your suppose to multiply a and c together, then find he greatest common factor from a and c(ac) 12x 2 +23x +5 a b c Ex:ac=12x5=60 B=23
- 4. Step 3: the you’re suppose to find the GCF to 60vand find a pair that adds up to 23. 12x 2 +23x +5 a b c Ex: ac=12x5=60 B=23 60, 1 20,3 30,2 15,4 12,5 10,6
- 5. Step 4: This is the final slide. When you find the answer that adds up to 23 your suppose to put them Into binomials, then finally solve them. 12x 2 +23x +5 (12x 2 + 20x+3x+5) a b c 4x(3x 1 +5)+1(3x+5) Ex: ac=12x5=60 (4x+1) (3x+5) B=23 60, 1 20,3 30,2 15,4 12,5 10,6
