Factor 18x(x²-5)^-4(x+1)^4+(x²-5)^-3(x+1)^3 Help Please

OpenStudy (mww):

bit confused by your powers here. Are those negative powers on the (x^2-5) factor?

OpenStudy (ronaldo7):

yup

OpenStudy (mww):

well there is more than one way to express it then. The general rule for factorising is to take out the lowest (i.e. less positive) powers as factors to start with.

OpenStudy (ronaldo7):

yeah

OpenStudy (ronaldo7):

but there are two different exponent values

OpenStudy (ronaldo7):

(x^2-5)^-4(x+1)^3[18(x^2-5)(x+1)] is this right?

OpenStudy (ronaldo7):

hello?

OpenStudy (vuriffy):

I thought mww was helping you. Sorry.

OpenStudy (vuriffy):

Can you rewrite the whole equation in clearer relevance so I understand completely.

OpenStudy (mww):

um close. you got the outside part right

OpenStudy (mww):

The inside should be (18x(x+1)+(x^2-5)) = (19x^2 +18x-5)

OpenStudy (ronaldo7):

how did u get to that
