## itsjustme_lol 2 years ago can someone help me out?

1. itsjustme_lol

(x+6)(x-6)

2. binarymimic

\[(a+b)(a-b) = a ^{2} - b^{2}\]

3. AonZ

what do u wanna do? lol simplify?

4. binarymimic

idk, maybe multiply it out? ?

5. itsjustme_lol

yeah i want to simplify it

6. binarymimic

try the difference of squares formula in reverse. its the same as FOILing but it results in a shortcut

7. itsjustme_lol

how do i do that? im confused. i was absent for this

8. binarymimic

i wrote it earlier let a = x and b = 6 in the formula

9. itsjustme_lol

10. itsjustme_lol

so if i did it the right way..i should have gotten x^2 -36??

11. AonZ

yes

12. binarymimic

if you were trying to solve it ? there is no equation to solve. what did you mean solve it ?

13. itsjustme_lol

idk? im confused now...i guess I had to solve it it? in order to simplify it wouldnt I have to solve it?

14. binarymimic

solve it means finding a solution to an equation simplifying means rewriting an expression if there is no equals sign its just an expression and there is nothing to solve for

15. binarymimic

were you given a value of x ? or was this expression equal to something ?

16. itsjustme_lol

nope it was just (X+^6(x-6)

17. binarymimic

oh ok.. sorry idk what to solve for. hm.

18. itsjustme_lol

sorry it was as I posted in the question. i didnt mean to put the ^6 its just 6. but hmmm then i guess i should just leave it as it maybe? confusing, i must say

19. binarymimic

yeah usually they just say "simplify" if there is no equation to solve for anything.

20. itsjustme_lol

could you confirm my answer on another one? (-8a3b4)2 5(-8)^2(a)^2(b^4)^2 5(64)(a^2)(b^8) 320(a^6)(b^8)

21. binarymimic

Where did the 5 come from ?

22. itsjustme_lol

sorry that was the number im on. idrk how it got there

23. binarymimic

oh if its not part of the question then.. 64(a^6)(b^8)

24. itsjustme_lol

hmmmm i wonder how i got 320...thankyou!!

25. binarymimic

well it looks like you multiplied your answer by the question # 5 o_o

26. itsjustme_lol

hahaha. gosh, that is what iget for staying up for 24+ hours :P

27. binarymimic

wow! get some rest!
