4-11x-3x^(2)=0

Solve the following quadratic equations by factorisation : (i) 4-11x=3x^(2) (ii) x^(2)-(11)/(4)x+(15)/(8)=0

Solve for x:2x^(4)+x^(3)-11x^(2)+x+2=0

2x^(4)+x^(3)-11x^(2)+x+2=0

Universal set, U={x|x^(5)-6x^(4)+11x^(3)-6x^(2)=0} A={x|x^(2)-5x+6=0} B={x|x^(2)-3x+2=0} What is (AnnB) ' equal to ?
