−4t2 + 64

OpenStudy (anonymous):

wow i got something different

OpenStudy (anonymous):

−4t2 + 64 = -4*(t^2 – 16) = − 4*(t – 4)*(t + 4)

OpenStudy (anonymous):

yes you are right I am just a fool.. $$t = \pm \frac84=\pm 4$$

OpenStudy (anonymous):

yep that's correct.

OpenStudy (anonymous):

mine or yours

OpenStudy (anonymous):

both

OpenStudy (anonymous):

I assumed equation..

OpenStudy (anonymous):

lol your not a fool can you check two more for me to see if i have them right

OpenStudy (anonymous):

sure where are they ?

OpenStudy (anonymous):

9 + 8t^2 – 18t = 8t^2 - 18t + 9 = (2t - 3)(4t - 3)

OpenStudy (anonymous):

do you see it

OpenStudy (anonymous):

looks good ..

OpenStudy (anonymous):

okay last one

OpenStudy (anonymous):

5x3+4x2−10x−8 = x2(5x+4)−2(5x+4) = (x2−2)(5x+4

OpenStudy (anonymous):

Factor by grouping, if possible

OpenStudy (anonymous):

$$5 x^3 + 4 x^2- 10 x - 8= (5 x+4) \left(x^2-2\right)$$ so again you are correct!

OpenStudy (anonymous):

tks FFM

OpenStudy (anonymous):
