Here is a list of the factoring techniques that we have discussed.
a. Factoring out the GCF
b. Factoring by grouping
c. Factoring trinomials by trial and error
d. Factoring the difference of two squares
A2 − B = (A + B) (A − B)
e. Factoring perfect square trinomials
A2 + 2AB + B2 = (A + B)
2 A2 − 2AB + B = (A − B)
f. Factoring the sum of two cubes
A3 + B = (A + B) (A2 − AB + B)
g. Factoring the difference of two cubes
A3 − B = (A − B) (A2 + AB + B)
Fill in each blank by writing the letter of the technique (a through g) for factoring the polynomial.
