Answer:
Step-by-step explanation:
Recall that the quadratic formula gives you the pattern to follow in order to find the solutions to a quadratic equation of the form: 
It tells us that we need to use the parameters 
and 
in the following formula in order to get the answers for the x-values that solve it:
so, in our case, 
, 
, and 
then, replacing these values in the formula, we obtain:
Which looks like the third expression you are listing (although it is a little hard to read)

Answer:
Amount of interest pay per year = $97.5 (Approx.)
Step-by-step explanation:
Given:
Amount borrow for college expenses = $3,897
Rate of interest = 2.5%
Find:
Amount of interest pay per year
Computation:
Using Simple interest formula;
Simple interest = Amount borrow x Rate of interest x number of year
Amount of interest pay per year = 3,897 x 2.5% x 1
Amount of interest pay per year = 3,897 x 0.025
Amount of interest pay per year = 97.425
Amount of interest pay per year = $97.5 (Approx.)
12= -12
-1/2= 1/2
.25 =-.25
-27=27
0=0
