Suppose A={−2,1,3,6,14}, B={−4,2,1,6,9}, and C={−2,6,9,12}. What is (A∩B)∪C?

(A∩B)∪C = 1, 6, 12

Step-by-step explanation:

Any values A and B share with along with any unique values of C

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
