    \[\sqrt{1-2b}=1+b\] \[\sqrt{1-2b}^2=1+b\] \[1^2-2b^2=1+b\] \[1-4b=1+b\] \[-5b=0\] \[-5b/-5=0/-5\] \[b=0\] Plug that back into the original equation and you will get 0=0 which is true

    she said the teacher gives examples in class but then the homework can not be done like the examples...i told her we would try to find someone online to help her understand hopefully (but she is doubtful) i hope you are the hero
