For what value of â€œkâ€ will the equation (2kx2 + 6kx +2)=0 have equal roots?	Choose one:	A) 2 / 7	B) 4 / 9	C) 16 / 25	D) 7 / 1	E) 7 / 2

Rationale: "for a 2 nd degree equation ax 2 + bx _ c = 0 has equal roots the condition is b 2 - 4 ac = 0 in the given equation ( 6 k ) ^ 2 - 4 * 2 k * 2 = 0 by solving this equation we get k = 0 , k = 4 / 9 answer : b"
Answer: B
