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?

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 (A nn B) equal to?

A={x|3x^2-7x-6=0},B={x|6x^2-5x-6=0} . Find A nn B

x^(3)-6x^(2)+11x-6=0

Solve 6x^5 -x^4 -43 x^3 +43 x^2 +x-6=0
