WebFor some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and squaring both sides of the equation … WebAgain, it is helpful to have some idea about what the graph will look like. Think about the basic square root function, f (x) = √x f ( x) = x. Take a look at a table of values for x and y and then graph the function. Notice that all the values for x in the table are perfect squares.
