Best ResponseYou've already chosen the best response.0oh right! My teacher made a typo, lol. they should both be r's. and no, I don't remember anything from algebra 1! Which is bad :/

Best ResponseYou've already chosen the best response.1How do you know they shouldn't both be x's?

Best ResponseYou've already chosen the best response.0well, letters don't really matter. whichever you replace, they would still be the same problem. just different letters.

Best ResponseYou've already chosen the best response.0You can also use the quadratic formula, which is faster i guess. \[\large x=\frac{(b)\pm\sqrt{(b)^{2}4(a)(c)}}{2(a)} \]

Hero

Best ResponseYou've already chosen the best response.1Nope, I'm faster. The quad formula is whack.

Hero

Best ResponseYou've already chosen the best response.1Mimi uses it because she can't factor :P

Mimi_x3

Best ResponseYou've already chosen the best response.0Nope, well..the using the quadratic you won't need to think much as to factor where you mgiht make stupid mistakes.

Best ResponseYou've already chosen the best response.1poor kid = poor little kid To me it's the exact same thing. A sympathy plea

Best ResponseYou've already chosen the best response.0Excuse me, its not a "sympathy plea" i never told you to be pity me. GOsh people these days who dont have common sense.

Best ResponseYou've already chosen the best response.0i don't remember crap about the quad form hah.

Mimi_x3

Best ResponseYou've already chosen the best response.0Because Hero is unable to factor it :P

Best ResponseYou've already chosen the best response.0\[\large c=\frac{(b)\pm\sqrt{(b)^{2}4(a)(c)}}{2(a)} \] \[\large c=\frac{(1)\pm\sqrt{(1)^{2}4(2)(10)}}{2(2)} \]

Best ResponseYou've already chosen the best response.1Quad Form is an even bigger fail, especially when you depend on it so much Mimi :P

Hero

Best ResponseYou've already chosen the best response.1I know about 5 different factor methods

Hero

Best ResponseYou've already chosen the best response.1None of which include the dreaded quad form

anonymous

Best ResponseYou've already chosen the best response.0how would you use the quad form on questions like 25m^264=0??

Mimi_x3

Best ResponseYou've already chosen the best response.0What? You dont have the right to say that its a fail since i got it right in the first go, not like you who go it WRONG! EVen during exams it would be a waste of time to do it again :P

Best ResponseYou've already chosen the best response.125m^2  64 = 0 25m^2 = 64 m^2 = 64/25 m = sqrt{64/25} m = plus or minus 8/5

Mimi_x3

Best ResponseYou've already chosen the best response.0I was trying to help her know a better method to solve it which is quicker. I was being nice

Best ResponseYou've already chosen the best response.1you just made one, then auto corrected it. Putting ax^3 , then ax^2. Such silly mistakes :P

Best ResponseYou've already chosen the best response.0its called a TYPO, you make stupid mistakes as well argh..i should never comment in questions that you are in anymore.
