Sample problem:

you have the solution with the explanation, so what else do you need?

I have a sample problem. I've tried applying the steps to the actual problem but it's confusing.

So instead of substituting 6 and 1 into the v's, you'll substitute 5 and 2.

The substitution takes place at the part where the expression is in square brackets. [ ]

Can you wait while I do it, and tell me if it's correct?

Yes.

I got 77.5 when I plugged in 5.

I got -7.5

There's an extra negative sign next to the red negative sign. Ignore the extra one.

\[{-3(5)^{2}\over 2}+6(5)\]

Okay, so if I plug in 1, I'll get -3/2+8 = 6.5

No. 4.5.

Look at the equation I wrote above.

What do you get when you evaluate that expression?

Oh, I forgot to square it.

Then I get: (-7.5+4.5) - (-3/2 +8) = -9.5 or -19/2.

It's cool.

It's not correct though.

6 and 1 are solely used in the example.

You never answered my question. What do you get when you evaluate the expression I wrote above?

-7.5

Replace BOTH 5s with 2s. Not just the one on the left.

Perfect. Now the last step is subtracting that 6 from -7.5:
-7.5 - 6 =

-13.5

Awesome : )

But if you look at the sample problem, they subtracted another part too.

I got -8 and it's still wrong.

-8 on which problem?

Ugh. It's + 8 not +6

\[{-3v ^{2} \over 2}+8v\]

Answer: -7.5 or -15/2

Okay

Sorry. I thought the expressions were the same in the example and actual problems.

It's okay. Can you help with another problem?

If you're not busy?

Sure.

Sample:

4/3

Then integrate each term.

\[[{2 \over 3}u ^{3/2}-8u ^{1/2}]\]
