Question

Need help with writing this code/solution in, at least, MatLab v. R2018b

Task 4.12 Using the command roots calculate the solutions of the equations 23 + 2a +r+1= 0 and – 2x + 25 + m2 = 4. Here you need to be careful that the coefficients of the polynomials are entered correctly as vectors.

Answer 1

Matlab code for finding roots

eq1 is

x³ + x² + x + 1=0

eq2 is

x⁵ + x² - 2x - 4 = 0

============================================================================================

Matlab code for finding roots

p=[1 1 1 1];
r=roots(p)

p=[1 0 0 1 -2 -4];
r=roots(p)
