@campbell_st

OpenStudy (datman21328):

Find the lcd

OpenStudy (18jonea):

What is that

OpenStudy (18jonea):

@Hero

OpenStudy (datman21328):

1/x is a multiple of x^3

OpenStudy (datman21328):

(1/x)x^4

OpenStudy (datman21328):

Is x^3

OpenStudy (datman21328):

(1/x)-(x^4/x)

OpenStudy (18jonea):

the equation is 1/x -x^3

OpenStudy (18jonea):

so how would i solve it?

OpenStudy (18jonea):

@zzr0ck3r

OpenStudy (zzr0ck3r):

write f(x) then write a minus sign and then write g(x)

OpenStudy (18jonea):

1/x - 3x^2

OpenStudy (18jonea):

so now what do i do

OpenStudy (18jonea):

@zzr0ck3r

OpenStudy (18jonea):

@UnkleRhaukus

OpenStudy (unklerhaukus):

\[f(x) -g(x) = \frac1x-x^3\] Done.

OpenStudy (18jonea):

so now i have to solve it

OpenStudy (18jonea):

@UnkleRhaukus

OpenStudy (unklerhaukus):

Solve for what?

OpenStudy (18jonea):

solve the equation

OpenStudy (unklerhaukus):

which equation?

OpenStudy (18jonea):

1/x -x^3

OpenStudy (unklerhaukus):

that is an expression, not an equation ( there is no equals sign )

OpenStudy (18jonea):

Solve the question below. is the directions

OpenStudy (unklerhaukus):

oh, ok

OpenStudy (unklerhaukus):

so you have \[\frac1x -x^3\] which is the same as \[\frac1x -\frac{x^4}x\] which simplifies to \[\frac{1-x^4}x\]

OpenStudy (unklerhaukus):

Which is the answer .

OpenStudy (unklerhaukus):

good work
