Answer:

  x = 1/2 or 2

Step-by-step explanation:

You can factor this as ...

  2x^2 -4x -x +2 = 0 . . . rewrite the middle term to enable factoring

  2x(x -2) -1(x -2) = 0 . . . . factor by grouping

  (2x -1)(x -2) = 0 . . . . factor out (x -2)

What is the intersection of yhe sets A={2,3,5,7,11}and B={5,11,13,15,17}?
xxTIMURxx [149]

The intersection of two sets A and B is defined as the set composed by the elements appearing in both A and B.

So, the intersection is

A\cap B = \{5,11\}

Because all the other numbers do not belong to both sets:

  • 2, 3 and 7 belong to A alone
  • 13, 15 and 17 belong to B alone
  • 5 and 11 belong to both A and B
