SOLUTION: Hi, I am solving with the quadraic formula and would like you to check my work and answer please. 3n^2-2n+5=0 -2 sqrt ((-2)^2-4(3)(5))/(2(3)) -2 sqrt (4-60)/(2) -2 sqrt (60

Question 409257: Hi, I am solving with the quadraic formula and would like you to check my work and answer please.
3n^2-2n+5=0
-2 sqrt ((-2)^2-4(3)(5))/(2(3))
-2 sqrt (4-60)/(2)
-2 sqrt (60)/(2)
-2 sqrt ((4)(15))/(2)
-2 +- 2 sqrt (15)/(2) is this final answer?
