Best ResponseYou've already chosen the best response.1If you put it back in the original equation, it does not make a true sentence.

Best ResponseYou've already chosen the best response.0ahhh... so i know on the2nd to 3rd step you skipped the math involved.. i get 3x=x^2+8x+10 am i correct?

Best ResponseYou've already chosen the best response.0well, would you count it or not because you could do 6,6 = 10+4, one of those is true

Best ResponseYou've already chosen the best response.0so you divide it all by 3... right? to get x alone?

Best ResponseYou've already chosen the best response.0but sqrt(36) also = 6, and 10 + 4 is 6, so  6 = 6 but 6 ~= 6

Best ResponseYou've already chosen the best response.1mridrik, did you look at the drawing I made? The square root symbol means the POSITIVE root

Best ResponseYou've already chosen the best response.0But why wouldnt you also accept the  root? 6^2 is also 36

Best ResponseYou've already chosen the best response.1Is that not the original problem? Do you see anything there about the negative root?

anonymous

Best ResponseYou've already chosen the best response.0the original problem says sqrt(3x+6) = x + 4, if x is negative ten, then sqrt(36) = x + 4, the square root of 36 is positive and negative 6, I'm just wondering why you dont use the negative six, I understand some problems just mean the principle square root, but how do i know when it means that?

Best ResponseYou've already chosen the best response.0that's a good question... i don't know?

Best ResponseYou've already chosen the best response.1Here is the original problem
