write the form of the partial decomposition for the given rational expression. Don't solve for constants:

8x+10/x^2+7x-18

please show work!

  • pre calc -

    I am pretty sure you meant:

    (8x+10)/(x^2 + 7x - 18)
    = (8x+10)/((x+9)(x-2))

    let This be
    A/(x+9) + B(x-2)
    = ( A(x-2) + B(x+9) )/( (x+9)(x-2) )

    so ...

    A(x-2) + B(x+9) = 8x + 10

    sub in A = 2, and B=-9 to find the constanst
