Assignment #$5$

Due date: Shown on the Blackboard.

Please submit:

$1.$ Your MATLAB code.

$2.$ Copy of a screenshot after your program is executed.

$3.$ Verification of your result using MATLAB function.

Create MATLAB code of Bracketing and Newton$$s Method that finds all roots of

the following equation $($Hint: There are four, integer roots for the equation.$),$ and

compare your result with the result from MATLAB provided function.

x$420$x$2+64=0$

You may want to start with the range big enough to cover where roots would exist

$(-30$ to $30$ with increment of $3$ would be a good start$).$

Use Bracketing Technique to narrow the range down.

Then, apply the Newton$$s method to refine the answer.

Verify your result using $$roots$$ function in MATLAB.
