For what value of â€œkâ€ will the equation (2kx2 + 3kx +2)=0 have equal roots?  Pick one.
A) 2 / 7 B) 9 / 4 C) 16 / 25 D) 7 / 1 E) 16 / 9

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 ( 3 k ) ^ 2 - 4 * 2 k * 2 = 0 by solving this equation we get k = 0 , k = 16 / 9 answer : e
Answer: E
