Best ResponseYou've already chosen the best response.0FOIL (4+v8) (4 v8) =16  4v8 + 4v8  8 = 8

Best ResponseYou've already chosen the best response.0@vi3tbloodxx you're wrong... (4+v8) (4 v8) =16  4v8 + 4v8  8 = 8 it should be (4+v8) (4 v8) =16  4v8 + 4v8  64v^2 =4^2(8v)^2 so from here we can see that there's no need to multiply and simplify... just use difference of binom formula : a^2b^2 =(a+b)(ab) \[\LARGE a^2b^2=(ab)(a+b)\]

Best ResponseYou've already chosen the best response.0a^2−b^2=(a−b)(a+b)\ in this equation (4+v8) (4 v8) a = 4 and b = v8 4^2  (v8)^2 gives 16  8 = 8

Best ResponseYou've already chosen the best response.0@vi3tbloodxx Still don't get what you're trying to say...O_o where's "v" how come (v8)^2=8 ???

Best ResponseYou've already chosen the best response.0the v stands for the square root of 8. When squaring a square root the result is the number inside of the square root.

Best ResponseYou've already chosen the best response.0v cannot be a variable due to the fact that variables stands behind the number. Also from the poster previous post, she been using "v" as a square root notation.

Best ResponseYou've already chosen the best response.0hold on... is \[\LARGE v8=\sqrt8\] or \[\LARGE v8=v8\] ?? "v" is a square root or just a letter?? !
