Problem b (PA2b.java) Write a program that solves a quadratic equation of the form: ar bor+c=0 Specifically, the user will input the values of a, b, and c. Your program must then calculate and output roots of the equation, following these rules. First, calculate the discriminant: d=b2 - dac If the discriminant is negative, the roots are imaginary. Print out a message informing the user this and stop the program. For example: Enter a b c: 1 14 Roots: imaginary COMP1000-Programming Assignment 2 If the discriminant is exactly zero, there is one root. Inform the user of this one root: -6/20. Yo must provide exactly two decimal places in your response, rounding as necessary. For example: Enter a b c Root: -2.00 1 4 4 If the discriminant is positive, there are two roots: and Inform the user of the value of the roots in increasing order of value (i.e. the smaller root first, followed by the larger) You must provide exactly two decimal places in your response, rounding as necessary. For example: Enter a b c 1 6 5 Roots: -5.00, -1.00 Note that the JUnit tests, and grading, will be very picky about exact spacing, spelling, capitalization, and number formatting
