What are the x-intercepts of the graph of the f(x)? Show your work.

anonymous · Answer

y=−16x2+60x+16

anonymous · Answer

But what would the x intercepts be? Sorry im not good at this.. lol

anonymous · Answer

neither am i XD
but hmm...lemme think a lil

anonymous · Answer

How did you come up with that then? Lol

http://www.mathpapa.com/algebra-calculator.html thats how i came up with it XD i didnt get it and im only fourteen so i went on my favorite site to get answers for math :3

anonymous · Answer

thats the easy way out XD

xapproachesinfinity · Answer

for x intercepts solve the quadratic equation
$$-16x^2+60x+16=0$$

anonymous · Answer

I'm not one who likes to just fail.. And right now I really just need an answer to this question before I'm timed out. This is my segment exam.

anonymous · Answer

How do I solve that? :/

xapproachesinfinity · Answer

quadratic formula or whatever other means you learned

anonymous · Answer

I honestly learned it a while ago and didn't expect it to be on this test.. I really just need an answer right now.

xapproachesinfinity · Answer

cannot give the answer dear, you have to work it out
see open study code of conduct

xapproachesinfinity · Answer

i can lead to work out that's all

anonymous · Answer

I really don't understand it enough to work it out. A lot of people get straight out answers on here, I try to work it out and learn it myself.

anonymous · Answer

Right now I just really can't get this question

xapproachesinfinity · Answer

$$x=\frac{-60\pm\sqrt{60^2-4(-16)(16)}}{2(-16 )}$$

xapproachesinfinity · Answer

don't tell me you forgot basic math too:)

anonymous · Answer

Can you just tell me the intercepts? There's more to the question, I just need to know that much. That's all I'm asking for.

xapproachesinfinity · Answer

can't the answer, besides, if it is a test that's more of a no answer
none of the other would give you the answer. open study has a code of conduct my dear

anonymous · Answer

Yeah thanks.

xapproachesinfinity · Answer

no problem good luck

anonymous · Answer

Yup

xapproachesinfinity · Answer

wondering...
part of your question says show your work, but then you are saying you just want the answer??

anonymous · Answer

Aye! I was thinking the same thing! O-O

anonymous · Answer

I'd figure it out based on the answer. But I really don't want to be going back and forth for no reason. Thanks anyways you two, have a good night.

anonymous · Answer

you too...i guess...O.o
