Algebra Problem

[Burple]

I'm stuck on this group of Algebra problems. I'm in 8th grade and I keep forgetting how to do it. Here's an example.

1/3Rad45

/ =Fraction and Rad is that square root sign.

Anyone?

O yeah you need to simplify it. Not solve.

Haha.  It's really not that hard.  I could probably do that a few years ago.  It doesn't take a rocket scientist to use a calculator :/

Wait--what?  Calculated it with a calculator, or your mind?

Try this on for size. I can solve it in 10 seconds. But since you're probaly younger than me, lets let you try it

(x²+5x)(-3x-7)
Its actually just using FOIL

[WhatevaGuy]

(x²+5x)(-3x-7)

<3 FOIL

Hm..
-3x³ - 15x² - 35x

Okay--is that right?
