int(x^(3)-x^(2)+x-1)/(x-1)dx

int(x^3+3x^2+3x+1)dx

"int(x^(3)+x^(2)+x+1)/(x+1)*dx

int(x^3(2x-1))/(x-1)dx

int (1+3x^2)/(x(1+x^2)) dx

int(x^(4)+3x^(2)+1)/(x^(3))dx

int(3x^(2)+1)/(x(x^(2)+1))dx

Consider int(x^(3)+3x^(2)+2x+1)/(sqrt(x^(2)+x+1))dx =(ax^(2)+bx+c)sqrt(x^(2)+x+1)+lambda int(dx)/(sqrt(x^(2)+x+1)) Now, match the following lists and then choose the correct code. Codes: {:(,a,b,c,d),((1),q,p,s,r),((2),s,p,q,r),((3),r,q,p,s),((4),q,s,p,r):}
