Activity 1.01: Solving a Quadratic Equation Using an Optimizer

Solution

Let's solve the following quadratic equation:

Figure 1.29: Quadratic equation to be solved

We already know that the solution to this quadratic equation is x=5.

We can use an optimizer to solve this. For the optimizer, x is the variable and the cost function is the left-hand side expression, which is as follows:

Figure 1.30: Left-hand side expression

The optimizer will find the value of x for which the expression is the ...
