How do you solve #sqrt(1-2t)=1+t# and check your solution?
Square both sides to get rid of the square root.
Recognize that we should move everything to the right side of the equals sign to get a complete quadratic function for this equation.
Take out common factor
Now we have our two values for
Now to check our possible solutions we substitute our values for
Lets start with
Square L.H.S. and R.H.S
