    you can use the long method or the synthetic division...

    let's use synthetic division: REMEMBER to solve for x of the divisor (in this case the divisor is x-2): wherein x = 2 (x-2=0) (x=2) |dw:1345775020773:dw|

    you need to become interested.... anyways... i guess you know why 2 is on that very left side... 4, 8, 0, then 19 because 4 has its variable x^3 (highest) 8 has its variable x^2 (second highest) 0 because there should be a variable x but since there's none it is zero 19 is at the end because it has no variable... the answer: (4x^2) +(19)/(x-2)

    the problem is (2y^3+14y^2+22y-15) / (y+4) it says to find the quotient

    just like on your first prob. y+4=0 y=?
