  • algebra -

    do long division
    *******_4x^2__- 8x___-7_________________
    (9x+3)/ 36x^3 - 60x^2 -87 x -21
    ********36x^3 + 12x^2
    ********-------------
    ************** -72x^2 -87 x -21
    ************** -72x^2 -24 x
    ***************----------------
    ********************* -63 x -21
    ********************* -63 x -21
    remainder = 0
    so 4x^2-8x-7
