First we need to write the factors of the polynomial. In order for 1, 4, and -3 to be roots, they need to be the x values that make the polynomial equal 0.
(x - 1) = 0
That would be the factor for x = 1 because when we plug 1 in for x we get 1 - 1 which equals 0.
Multiply all the factors together.
(x-1)(x-4)(x+3)=0
Now FOIL.

Step-by-step explanation:
Answer:
T´(z)=n^2s/4*i
Step-by-step explanation:
T(z)=d/dz(sin^2*z/4)
T´(z)=d/dz(sn^2zi/4)
T´(z)=d/dz(sn^2z/4*i)
T´(z)i*d/dz(sn^2z/4)
T´(z)=n^2s/4*i
Simplify
Answer:
2019.
Step-by-step explanation:
We have been given that for the years from 2002 and projected to 2024, the national health care expenditures H, in billions of dollars, can be modeled by 
where t is the number of years past 2000.
To find the year in which national health care expenditures expected to reach $4.0 trillion (that is, $4,000 billion), we will substitute 
in our given formula and solve for t as:
Take natural log of both sides:
So in the 18.5 years after 2000 the expenditure will reach 4 trillion.
Therefore, in year 2019 national health care expenditures are expected to reach $4.0 trillion.
