- We solve the quadratic equation.
- By clicking on the tabs at the top we can see all the transformations
- we have carried out.
-
- Step 1. Notice the way in which we introduced the discriminant symbol (Delta,
- CTRL+d). To let the program know that this is just an auxiliary variable we
- use the substitution symbol - an arrow (CTRL+=).
-
- Step 2. When we subsequently use a predefined variable again,
- we use the equality sign =.
-
- Step 3. If the equation has more than one solution, we write them using the
- connective OR. Of course we could break down the problem into cases
- (SHIFT+y) and enter each solution separately.
-
- Giving the final answer is left to the user.
