Best ResponseYou've already chosen the best response.12[x1]4=2? put x=0 2[01]4=2*(1)4 =24=6 since 6 is not equal to 2, 0 is not a solution now try with another number lets take x=2 now 2[21]4=2*14 =2 since 2 is equal to 2 x=2 is a solution similarly consider other values of x which satisfies the equation and add all those which satifies the equation

Best ResponseYou've already chosen the best response.0Yes thank you very much! Seeing it broken down was very helpful! This is my last class before I graduate and its a big pain in the butt!

Best ResponseYou've already chosen the best response.0and the add 2 to each side came from the 4?

Best ResponseYou've already chosen the best response.1on the right hand side 2 is negative so 2+2 will be 0

Best ResponseYou've already chosen the best response.0okay I understand now. When I do future equations like this I just need to plug in the multiple choice option and see if its equal

Best ResponseYou've already chosen the best response.1or u can do like this 2[x1]4=2 add 2 on both sides then u will get 2[x1]4+2=2+2 2[x1]2=0 again add 2 on both sides then u will get 2[x1]=2 divide by 2 the equation will be x1=1 add 1 on both sides x=2

Best ResponseYou've already chosen the best response.0\[\large\rm 2014=2\]Absolute value of 1 is 1,\[\large\rm 2(1)4=2\]\[\large\rm 2=2\] @shaik0124 Is true, so x=0 `is` a solution. They wanted the `sum of the solutions` though, 2 + 0 = 2, so missing that doesn't really affect your answer :)
