## anonymous one year ago Please can somebody help me? i completely forgot how to do this D: Rewrite the expression by factoring out (y+6) 5y^2(y+6)-7(y+6)

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

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

3. jdoe0001

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

4. jdoe0001

say.. how factor say for example abc + abd = ?

5. anonymous

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

6. jdoe0001

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

7. anonymous

yeah, numbers you multiply to get other numbers right?

8. jdoe0001

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) ?

9. anonymous

a and b?

5y^2(y+6)-7(y+6) factor out (y+6) (y+6)(5y^2-7)

nice, thank you so much
