first you need to extract the value of x on the denominator 4x + 5 = 0 4x = -5 x = -5/4

Now write it like long division, except eliminate the x's and just write the coefficcients like you write synthetic division.

then you drop the 4, do (-5/4)*4 and put that under -7 and subtract or add?
darkprince14
  • darkprince14
depends on the sign..if it is negative you subtract.. if positive, you add..
darkprince14
  • darkprince14
if both of them possess the same sign then you add them then copy the sign..

  • darkprince14

  • anonymous
-5/4 * -12 = 15 so -11 + 15 = 4
