Help me factor x^2 + 9

x 2 + 9  has no (Real) factors (Unlike  x 2 − 9 )

Explanation:

The most you could do with this is use the quadratic formula on

x 2 + 0 ⋅ x + 9

to get

± 3 i

So you could factor using Complex values:

x 2 + 9 = ( x + 3 i ) ( x − 3 i )

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
