EQUATION
1. The equation 2x
2
+ 40x =150 was previously solved in the Graph menu. It can also be solved in the Equation menu by
transforming it to -2x
2
+ 40x -150 = 0 .
Press pf(A). (It is not necessary to push a.) To solve polynomial equations, press w(POLY). Press q(2) for a second degree
polynomial.
Enter the 3 coefficients, pressing l after each one. Note, equations must be in standard form to solve. To solve, press q(SOLVE). Both solutions are displayed. Note,
when solutions are not rational, both a decimal and an exact
solution are displayed. The third screenshot displays the solutions to .
