$\bf 5y^2({\color{blue}{ y+6 }} )-7({\color{blue}{ y+6 }} )\implies ({\color{blue}{ y+6 }} )[\square ?-\square ?]$

i dont understand u.u what is the answer? @jdoe0001

jdoe0001 · Answer

lemme put it this way

do you know how to do common facotoring?

anonymous · Answer

i really dont get, its just it has been a long time since i do this, and now i have to do a math class online but im really struggling with this question :( @jdoe0001

jdoe0001 · Answer

well.. do you know what a "factor" is?

anonymous · Answer

yeah, numbers you multiply to get other numbers right?

jdoe0001 · Answer

well
values or objects really
numbers just happen to be numeric objects
so a variable is also an object

so.... common factor is a "factor" that is common to all terms

so... what do you think about    abc + abd = ?
or 
(a * b * c) + (a * b * d)    <--- what's the common factor(s) ?
