What property are these? Associative property of addition, Commutative property of addition, identity property of multiplication, Associative property of multiplication, Commutative property of multiplication. 1. (3 x 7)(8) = 3(7 x 8) 2. (7k)5 = 5(7k) 3.8(x + 15) = (8)(x) + (8)(15)

Solve for x by completing the square. 2x^2-4x+7=0
