Question

Quadratic roots. Write a program, quadroots.m, for finding the roots of the second- order polynomial ax2 + bx + c. Use the quadratic equation. The inputs are the coefficients a,b, and c and the outputs are z1 and z2. The program should produce (exactly) the following output in the Command window when run with (a, b, c) = (1, 2, −3):

a=input('a= ');
b=input('b= ');
c=input('c= ');
disp('roots');
z1=(-b+sqrt(b^2-4*a*c))/(2*a)
z2=(-b-sqrt(b^2-4*a*c))/(2*a)

Kindly revert for any queries

Thanks.
