Opening ▪
1. Check for a GCF – if one is present, take it out and place in front of the problem. Then continue with factoring steps below: 2. Multiply A and C. 3. Replace the existing C with the number from step 2 and eliminate A. 4. Write out the factors of C. 5. Pick a pair of factors that combine together to equal B by addition or subtraction. 6. Choose signs for your factors that will yield the signs for B and C. 7. Divide the factors by the original A and simplify if possible. 8. BOTTOM’S UP – flip fractions to put the denominator in front of the variable.
