Solve the equation f ( x )= x2 -4 x +3=0. In this case, we can "factor by guessing": x2 -4 x +3= ( x -1) ( x -3), so the roots of the equation f ( x )=0 are x =1 and x =3. Draw a picture of the x -axis and mark these points. Step 2. Our solutions partition the x -axis into three intervals.

WebSolving an equation symbolically means that expressions can be used for representing the solutions. For example, the equation x + y = 2x – 1 is solved for the unknown x by the expression x = y + 1, because substituting y + 1 for x in the equation results in (y + 1) + y = 2 (y + 1) – 1, a true statement.
