how can i write this program i need only the method to write it>>>>

Say that you are interested in the value of the quadradic:
3X2 -8X + 4
For several values of X. Write a program that has a double precision variable X. Assign a value to it. Write statement that computes a value for the quadratic and stores the result in another double precision variable. Finally write out the result, something like:
At X = 4.0 the value is 20.0
Run the program with several values for X (edit the program for each value of X) and examine the result. Use values with decimal points, large values, small values, negative values, and zero. The quadradic should evaluate to zero at X = 2.0 and at X = 2/3. Try these values for X. Are the results exactly correct?
