Are sets `A= {-2,2},B={x:x in Z ,x^2 -4 =0}` equal ?Why?

Are sets A = { –2,2}, B = { x : x ϵ Z, IxI-2 = 0} equal? Why?

Find the sets which are equal, from the following sets : A = {2,1,3} B = {x : x^(3) - 6x^(2)+11x - 6 = 0} C = {0,1},D={a,b} E = {x : x^(2) - x=0} F = {x : (x-a)(x-b)=0} .

Are the following pair of sets equal? Give reasons A={2,3},B={x:x is a solution of x^2 +5x+6=0}

Are the following pairs of sets equal ? Give reasons. A={2,3}, B={x:x is solution of x^2+3x+2=0 }

Are these sets equals? A={x:x in Z and x^(2)<=4}B={x:x in R and x^(2)-3x+2=0}

Are the following pari of sets equal? Give reasons A= {x : x in Z, x^(2) le 8} B= {y : y in R, y " is a solution of "y^(2)-4y+3=0}

Find the pairs of equal sets from the following sets , if any, giving reason : A={0}, B= {x:x>15 and x<5} , C={x:x-5=0}, D ={x:x^2=25}, E={x : x is an integral positive root of the equation x^2-2x-15=0 } .

Find the (a) union (b) intersection of the following pair of sets : A = {x : x in Z^(+)} , B= { x : x in Z and x<0}.

If A = {x: x in Z and x ge 2} , B= {x: x in Z and x le 4} , then A cap B is equal to:

If A={x:x^(2)-2x+2gt0}andB={x:x^(2)-4x+3le0} A - B equals
