1.8. Writing Comments
To write a note next to the equation you are solving e,g answer to problem 1, function 1, problem 2; tap the division bar ( / ) twice, then write your comment. Enter one equation per workspace.
In the following screenshot, the next equations entered into the same window would be marked "false". The app automatically evaluates these equations using the value obtained from the first equation keyed in.
Examples
Solve the following equations. Then, identify the type of equation. Write it beside your solution.
1) 2x – 3 = 5
2) x^2 – 4x + 4 = 0
3) /2x + 1/ = 5
4) 2x^3 – 3x^2 – 5x = –6
Solve the following equations. Then, identify the type of equation. Write it beside your solution.
