I dont know if any of you will take the time to figure it out but everytime i do it, its wrong

6n^2-87n+180

____________

(n-12) x (n+15)

A:6n-15

-------

n-12

B: 6n-15

--------

n+15

C: n-12

------

n+15

n-15

-------

n+15

Update:

please help!! im getting so stressed out

ranjankar

6n^2 - 87n + 180

3 ( 2n^2 - 29n +60)

COEFF of n^2 = +2

( + 2) ( +60) = +120

FIND FACTORS OF +120 which add up to -29 ( COEFF of n)

( -24 ) ( -5) = +120

3 ( 2n^2 -24n -5n +60)

3 ( 2n (n -12) -5( n -12) )

3 ( 2n -5) ( n -12)

3 ( 2n -5) ( n -12)

---------------------------

(n-12) x (n+15)

ANSWER is B = (6n -15) / ( n + 15)

david

(6n^2 - 87n + 180) / [(n - 12)(n + 15)]

[(6n - 15)(n - 12)] / [(n - 12)(n + 15)]

(6n - 15) / (n + 15)

=(6n-15)(n-12)/[(n-12)(n+15)]

=(6n-15)/(n+15)
