Ineed on factoring polynomials. x^2- 2x - 24

In this question, we have to factor the given polynominal which is

We need two factors of -24 whose sum is -2, and -6+4=-2

So we can write f(x) as

f(x) = (x-6)(x+4)

And that's the required factored form .

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
