8. Solving Equations
Equals Sign
Use the equals sign ( = ) when solving equations to separate the left hand-side from the right-hand side of the equations. In Graph mode, if the function is written in the form "y =" you only need to write the relevant expression.
Example
Solve for x in the equation 2x² – 18 = 0
Calculator solution
Type the equation as given.
