Also can you included the name of every text box.
You are asked to develop a Visual Basic.Net application that can determine roots of a quadratic equation. The functional requirements of this project are as follows: 1) Design a form to allow users to define a quadratic equation. The form should have a textbox control created from the textbox control template (see Figure 4-3). This textbox control will allow users to enter a quadratic expression. For example, if we want to determine the roots for *+2x+1=0 The textbox control should allow users to enter in the quadratic expression in it: 1x^2 + 2x+1 H. Quadratic Equation Enter a quadratic equation F(x): 1x^2+2x+1 X1: Calculate Clear Cancel 2) Figure 4-3 An Example Form for the Project When a quadratic equation is entered in the textbox, the parameters (a, b, and c) of the expression should be extracted when users enter the Enter key. The extracted parameters are then displayed in the textboxes for them. respectively. Hint: You need to use the KeyPress event to respond to the Introduction to Computer Programming & Numerical Methods 55 textbox for the quadratic equation. For example, when the textbox is named Func, the event procedure to respond to the KeyPress event will be as follow: Private Sub Func_KeyPress (ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPress EventArgs) Handles Func. KeyPress End Sub 3) More information about how to respond to the KeyPress event is provided in Chapter 5. When you are working on this project, you should read Chapter 5 to get a better understanding of VB.Net statements that are related to this project Once the parameters a, b, and care extracted from the quadratic equation and displayed in the three designated textboxes, you are asked to calculate the roots and display them on the form. The VB.Net application should have extensive checking capabilities to ensure the roots are calculated accurately. The application should be able to determine both real and imaginary roots Step by Step Solution
