Answer 3

Tell me whatcha get and I'll help you out if you need it. It kinda gets confusing with those square roots, I know!

Answer 4

@Kainui 6 sqrt5 - 9 sqrt5 + 2 sqrt5 - 2 thats what i got after i did F.O.I.L <---- i think thats wrong

Answer 5

Alright, so first off we can take it one at a time. First we multiply \[(3\sqrt{5})*(2\sqrt{5})\] which will give us \[(3*2*\sqrt{5}*\sqrt{5})\] Now we can see that 3*2 is 6, and we see that \[\sqrt{5}*\sqrt{5}=\sqrt{5}^2=5\] right? So they just cancel each other out! So for our first term the answer is: \[6*5=30\]

Answer 6

With me so far? Or should I keep going?
