Yes I am
I am as well. I had trouble on a question like this ask @johnweldon1993 he'll probably be more help here.
thanks
So we first start with the restrictions...they can come up at ANY point of our simplification process.. So restrictions here would be whatever 'x' values make the denominator = 0 (in either fraction) what would those be?
Hint would be to factor the denominators :)
oh ok give me a sec
ok so the first one factored would be (x+4)(x-1) and I have to find what x would be to make this equal 0?
Correct
it would be -4 and 1
Okay great...2 restrictions down so far But...what about the other fraction now?
so you said I just have to do it for the denominator?
mmhmm, we know dividing anything by 0 makes for an undefined answer...so whenever denominators = 0 we have a restriction
alright so for this one it would be -4 and -1
That is correct...and yet I dont see any answer choices with a -1 as a restriction...odd...but oh well, aybe they just missed one Okay so now we begin to simplify...how would we begin?
none of my answer look right with this... are you sure this is how you do it?
the restrictions should be -4, 1, -1 but those aren't in any answers
Yup. Find restrictions...then simplify..and I know thats why I was confused as to why the -1 wasnt there And we also will have more restrictions in a little bit
ok well how do I start to simplify?
Well the first thing I would do....is turn this into multiplication...we would do that by flipping the second fraction \[\large \frac{5-x}{x^2 + 3x - 4} \times \frac{x^2 + 5x + 4}{x^2 - 2x - 15}\] make sense?
\[\frac{ 5-x }{ (x+4)(x-1) } \ \times \frac{ (x+4)(x+1) }{ (x+3)(x-5) } \]
so like this?
Perfect...and NOW we simplified...we need to check for any more restrictions!!
ok so -3 and 5?
Right...so literally in total...we SHOULD have 5 restrictions on the problem...but they only give us 4
huh ok
so its B?
It would be ye...you simplified and got that right?
well its the only one with the correct restrictions. and yes I simplified to the point of knowing it couldn't be the other ones
thank you so much ^.^ a medal and a hug for you *hug* lol
Well thank you but the hug was the best part! :P lol
haha well you're honestly the first I've ever given a hug for helping me :P ^.^
