Step-by-step explanation:
if A=(0), B =(X:X>15 and x<5), c=(x:x-5=0), D=( x:x2=25) E=(x :xis a positive integer root of equation x2-2x-15 =0, then pair of equal sets is : A ...
Top answer
A = {0} B = {0} as no such element s.t x>15 and x<5 C = {5} x:x - 5 = 0 D = { - 5,5} x2 - 25 x = - 5,5 E = { - 3,5} Roots of the equation x2 - 2x - 15
