Using the quadratic formula to solve 2x^2 = 4x – 7, what are the values of x?

For this case we have the following quadratic equation:

Rewriting the equation we have:

From here, we have:

Substituting values in the quadratic equation we have:

Rewriting the equation we have:

The values of x are given by:

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
