Find the solutions of the quadratic equation

x =

Step-by-step explanation:

x equals -b plus or minus square b squared minus 4 ac all over two a.  Sing the song.

3x^2 + 9x + 17 = 0

a = 3

b = 9

c = 17

x =

x =

x =

x =

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
