Best ResponseYou've already chosen the best response.0okay, then let me ask you some questions do you know what a "rational" number is ?

Best ResponseYou've already chosen the best response.0it is a long story if we went through the details, but the shortest way to say it is "fractions"

Best ResponseYou've already chosen the best response.0so 0.1 is rational since it is 1/10 0.7878787878... is rational since it is 78/99 10 is rational since it is 10/1

Best ResponseYou've already chosen the best response.0what you did was probably \[(x1)^2 = x^2 2x +1\]

Best ResponseYou've already chosen the best response.0the step you took is called "expanding" the opposite step is called "factoring" so for example \[x^2 +5x +6 = (x+2)(x+3)\]

Best ResponseYou've already chosen the best response.0my mistake. i know how to factor and expand and what not. im just having trouble factoring that equation

Best ResponseYou've already chosen the best response.0if i can get that factored then i believe i will be able to solve the rest of the equation.

Best ResponseYou've already chosen the best response.0okay, I just want to demonstrate the difference between a), b), and c), so bare with me. could you factor \[x^21\]
