(need matlab code as well)

Ask the user to enter the values for the three constants of the quadratic equation (a, b, and c). Use an if-else if-else-end structure to warm the user if b^2 - 4ac > 0, b^2 - 4ac = 0, or b^2 - 4ac = 0, determine the solution. Use the following to double-check the functionality of your function: a. Use a = 1, b = 2, c = -1 b. Use a = 1, b = 2, c = 1 c. Use a = 10, b = 1, c = 20
