How do a write a program using the quadratic formula in JGrasp?
Write a program named QuadraticTable.java that takes three double arguments and two int
arguments (in that order) from the command line. The three doubles will represent a, b, and c
from the quadratic formula.
If the discriminant is nonnegative, find and print the solutions to the quadratic equation. (The
plus/minus sign in the quadratic formula indicates that you would separately perform both
operations). Otherwise print “no real solutions”
Then using the last two int arguments as x_min and x_max, print a table of x and 𝑎𝑥
2 + 𝑏𝑥 + 𝑐
values using the a, b, and c read in as command line arguments.
Sample output: (command line arguments were 1 0 2 3 3)
1x^2 + 0x + 2 has no real solutions.
X 1x^2 + 0x + 2

Re: How do a write a program using the quadratic formula in JGrasp?
First, you are not writing the program in JGrasp. You are writing the program in Java. JGrasp is an IDE and has no bearing on the actual code. Now, just post your code and explain where you are having problems. Then we can help you.
