variables, or let the calculator provide a solution. (Typically a

seed value is a value that directs the calculator to provide, if

possible, a solution that is closest to it rather than some other

value.) In this example, let’s look for a solution in the vicinity

of X = 2.

5. Enter the seed value in the X field:

The calculator will provide one solution (if there is one) and

you will not be alerted if there are multiple solutions. Vary the

seed values to find other potential solutions.

6. Select the variables you want solutions for. In this example

we want to find values for both X and Y, so make sure that

both variables are selected.

Note too that if you have more than two variables, you can

enter seed values for more than one of them.

variables

7. Tap to find a solution

near X = 2 that satisfies

each selected equation.

Solutions, if found, are

displayed beside each

selected variable.

Limitations

You cannot plot equations if more than one is selected in

Symbolic view.

The HP Prime will not alert you to the existence of multiple

solutions. If you suspect that another solution exists close to a

particular value, repeat the exercise using that value as a seed.

(In the example just discussed, you will find another solution if you

enter –4 as the seed value for X.)

In some situations, the Solve app will use a random number seed

in its search for a solution. This means that it is not always

predictable which seed will lead to which solution when there are

multiple solutions.
