%this is the code

syms x;
y1=2*x^3-x+8;
y2=15*x^2-17*x-4;
disp('At the Intersection both the curve point will be same');
At the Intersection both the curve point will be same
disp('Therefore equating both the curves : 2*x^3-x+8 = 15*x^2-17*x-4 ');
Therefore equating both the curves : 2*x^3-x+8 = 15*x^2-17*x-4 
disp('Equation becomes : 2*x^3-15*x^2+16*x+12 = 0');
Equation becomes : 2*x^3-15*x^2+16*x+12 = 0
p=[2 -15 16 12];
r=roots(p);
x=r;
y=[0 0 0];
y22=[0 0 0];
for i=1:3
    x1=x(i);
    y(i) = 2*x(i)^3-x(i)+8;
    i=i+1;
end
disp('The intersection points are : ');
The intersection points are : 
for j=1:3
    fprintf('(%.2f,%.2f) ',x(j),y(j));
end
