    Undergrad What is the Value of (p+q-2t) and (p^2+q^2-2t^2) in an Equation with Degree 3?

    I know p+q+t=c/2 pq+pt+qt=(b-3)/4 pqt=(2c-a)/8 but I need value for (p+q-2t)?? (p^2+ q^2-2t^2)? Please help me??

    Undergrad What is the Value of (p+q-2t) and (p^2+q^2-2t^2) in an Equation with Degree 3?

    I have an equation similar: 8x^3+4cx^2+2(b-3)x+(a-2c)=0 a, b, c are real number. if p, q , t be roots. What can say about (p+q-2t) and (p^2+ q^2-2t^2)? Please help me?? Thanks so much.
