For what value of â€œkâ€ will the equation (2kx2 + 4kx +2)=0 have equal roots?	Pick: A) 1 B) 9 / 4 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 ( 4 k ) ^ 2 - 4 * 2 k * 2 = 0 by solving this equation we get k = 0 , k = 1 answer : a"
Answer: A
