in part first, sect is given equal to two comma three and equal to X. Such that X. Is a solution of ax squared plus five X plus six equal to see. So first of all we simplify this equation X squared plus five eggs Plus six equal to see you. So here we get access square plus three eggs. There's two eggs Plus six equal to zero X. Times x plus three plus two times explodes three equal to zero. So our factories X plus two time X. Close three. So here X equal to negative two And x equal to 93. So now here said we Is, -2, -3. And our state E. Equal to to Coma three. So you can see that here we have different elements in set A. And set B. So here we can say said A. Is not equal to said be so it is a answer. Now we sold part 2nd said A. Is given. Except that ex is a letter in the world follow and said be equal to why such that way is a letter in World Wolf. So here we can arrange in roster form F. Goma, Oh, Goma, L, coma W. And be equal to W. Coma. Oh, coma L, coma F. So you can see that here said A and B. How some elements. So here we can say A equal to be so it is our final answer.
