Write a MATLAB program to compute both roots of the quadratic equation as you input the values of a, b, and c. &nbsp Requirements:

a) Use “input” to ask the user to put in the values of a, b and c
b) Use “if” structure to avoid division by zero and complex roots
c) Print out the roots for the following situations:
   (1). a=2, b=10, c=12
   (2). a=0, b=10, c=4
   (3). a=4, b=10, c=100

Do you actually have a question, or do you just want us to do your homework for you?

在 MATLAB Online 中打开

   function r = findQuadraticRoots(a,b,c)
       if something is true
            do some stuff;
       else
            do some other stuff;
       end
    end
