Answer 1

partial fractions or does the denominator not factor?

Answer 2

Answer 3

no it doesn't factor. i guess you have to complete the damned square

Answer 4

oh i didn't see the radical, sorry

Answer 5

no intervals, just inegration. somebody please help me

Answer 6

Answer 8

ohh ohh ohh okayy,, yeaaa i got it i got . thankyou...

Answer 9

it is a colossal pain but doable i would cheat
