@campbell_st probably has a better way of explaining the factoring but i also have a method and both will work. mine is just slightly confusing to some people

OpenStudy (campbell_st):

well each pair of factors give the constant and leading term when multiplied... so check which pair results in 10x so if you use FOIL.... see which inside + outside = 10x

OpenStudy (anonymous):

how do you use FOIL

OpenStudy (anonymous):

ya that too just solve the answers, what gives you your original equation

OpenStudy (anonymous):

NEVER HEARD OF foil

OpenStudy (anonymous):

FOIL is the short way of saying first, outer, inner, last

OpenStudy (anonymous):

that asks you to multiply the first two terms, then the outer two terms, and then the inner two terms, and then the last two terms of your parentheses

OpenStudy (anonymous):

please explain
