Can you please solve the quadratic equation first? I mean to find that value of a when the equation is 0

ya im pretty sure it's \[a^25a2a+10\] After it's been factored it's \[(a5)(a2)(a5)(a2)\]

Not quite..

No repeated factors in this case.

sgta101 Group TitleBest ResponseYou've already chosen the best response.0
so just \[(a−5)(a−2)\] ?

RolyPoly Group TitleBest ResponseYou've already chosen the best response.1
There are four factors :)

dw:1358566081932:dw So, the graph is like this (sorry for my poor drawing..) In what region does the function have a value less than 0?

i think i got it from here. one more thing does \[(a^25a2a+10)^2\] become \[(a^27a+10)(a^27a+10)\]?

RolyPoly Group TitleBest ResponseYou've already chosen the best response.1
Are you still working on the factorization part?

ya im making sure how i got the wrong answer.

sgta101 Group TitleBest ResponseYou've already chosen the best response.0
i think i messed up in the factorization

\[a^4  29a^2 +100\]\[=a^4  25a^2  4a^2 +100\]\[=a^2 (a^225) 4(a^2  25)\]\[=(a^24)(a^225)\]\[=(a2)(a+2)(a^225)\]\[=(a2)(a+2)(a5)(a+5)\] The last two steps are just using the identity of difference of two squares. \(a^2b^2 = (a+b)(ab)\)

RolyPoly Group TitleBest ResponseYou've already chosen the best response.1
I don't know how you get this: \[(a^25a2a+10)^2\]
