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)
44-41=3 hope it help think so
//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root
Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3
1 hour = 60 minutes
2 3/4 hours = 165 minutes
