1) Build a MATLAB function to solve the quadratic equation with variable x using where the number of outputs is two value and the input is one value as a vector. For example: ax2+bx+c=0; the inputs will be [a b c] The results will be x1,x2 x1,x2=2abb24acEq(1) 2) Then check your script file by this equation x2+10x+9 to obtain x1 and x2 and check your answer using roots commands 3) Plot the above equation (Using polyval commands) within this interval x1x x2 where x1
