choices
OpenStudy (anonymous):
4k^2 right ?
OpenStudy (anonymous):
2(k + 5)2
(2k – 5)2
(2k + 5)2
4(k + 5)(k – 5)
OpenStudy (anonymous):
D
OpenStudy (anonymous):
is that 8k in the beginning?

Yea should it be 8k^2 ?
OpenStudy (anonymous):
oh it's squared
I thought it was 4*2
OpenStudy (anonymous):
Nope it's actually A
OpenStudy (anonymous):
Let's factor A and find out ..
OpenStudy (anonymous):
2(k+5)^2 right ?

I say (2k+5)^2
OpenStudy (anonymous):
great minds think alike
OpenStudy (anonymous):
No your's is actually different though
OpenStudy (anonymous):
hmmmmm Maybe my mind is not so great. And my eyes
OpenStudy (anonymous):
2(k+5)^2 = 2(k^2+10k +25) = 4k^2 + 40k + 100)

think I'm right on this one
OpenStudy (anonymous):
that's not the correct factored form that the question asks though it's 4k^2 + 20k + 25 so I disagree again
OpenStudy (anonymous):
I used your answer
OpenStudy (anonymous):
slow down and re read your method is correct though
OpenStudy (anonymous):
I expanded your answer

Okay @norbet123 needs to be more specific with the question and even if you did it your way it's still wrong
OpenStudy (anonymous):
(2k+5)^2
OpenStudy (anonymous):
but if you expand (2k+5)^2, you get the 4k^2+ 10k +25
OpenStudy (anonymous):
which is the original polynomial
OpenStudy (anonymous):
sorry 20k

Okay I see now sorry I agree now the parenthesis is very important here 2 is inside not outside .. sorry
OpenStudy (anonymous):
All good. :)
