\[\frac{ x^{4}+x ^{3}}{ x}\]
geerky42 (geerky42):
Try to factor numerator. What do both terms in numerator have in common?
OpenStudy (anonymous):
x
geerky42 (geerky42):
Yup so factor it out.
OpenStudy (anonymous):
x^7

x^7/x?
geerky42 (geerky42):
no, just factor it out, like for example: factor a out from a² + a³ \(\Rightarrow\) a(a + a²)
geerky42 (geerky42):
Confused?
OpenStudy (anonymous):
x(x^3+x^2)?

beyond!! math is not my strongest suit. :(

@bahrom7893 would you be able to help me? I'm stuck
OpenStudy (jim766):
\[\frac{ x^3(x+1) }{ x } \]
OpenStudy (anonymous):
@Jim766 how so tho?
OpenStudy (anonymous):
(x^4+x^3)/x = x^3 + x^2 how did I end up with this? agh! I'm confused! :(

OpenStudy (jim766):
x^4 = x*x*x*x + x^3 = x*x*x
they both have x^3 in common
OpenStudy (jim766):
then it reduces to
x^2(x+1)
OpenStudy (anonymous):
so my answer would be x^2(x+1)/x?
OpenStudy (jim766):
\[x^4 + x^3\]
greatest common factor is \[x^3\]
now divide x^4+ x^3 by x^3 to factor it out
x^4 + x^3
--- ---- = x^1 + 1
x^3 x^3
x^3(x + 1) = x^4 + x^3
