Displaying a quadratic equation

Hi im very new to Matlab and help would be greatly appreciative

Consider the quadratic equation of the form: ax^2 + bx + c = 0, where a,b,c are constants

(a) Write a MATLAB function having the coefficients a, b, c as input arguments to determine the quadratic roots of the equation. Specifically, display the two roots in the Command Window using the following format:

The first root = r1 The second root = r2

(b) Utilize the function created in part (a) to find the roots of the quadratic equations specified by the Lab TA. Tabulate the results.

This a homework. What have you done so far? What problem have you encountered?

function parallel = parallel® R=(1e4); rp(1,1) = R; for n = 1:99 rp(n+1) = (rp(n)*R)/(rp(n) + R); bar(rp) end n = 1:100; plot(n, rp(n))

I got the answer I was missing a semi colon that why i was getting an error

The roots() command will be helpful, see "doc roots" for usage. The disp command should also help, e.g,

>> disp(['Here is a number, ', num2str(3), '. It is the number three.'])

displays,

Here is a number, 3. It is the number three.

I got the answer I was having problem with a simple problem i was missing a semi colon lol

function parallel = parallel® R=(1e4); rp(1,1) = R; for n = 1:99 rp(n+1) = (rp(n)*R)/(rp(n) + R); bar(rp) end n = 1:100; plot(n, rp(n))
