1984-1994 the equation the number of aids cases can be modeled by the equation

C(x)=3034x^2+14,018x+6400

X represents years after 1984 estimate the year when 200,000 aids cases had been diagnosed.

X=1990

• college algebra -

3034x^2+14,018x+6400 = 200000
3034x^2+14,018x - 193600 = 0
use the formula, you are just dealing with large numbers, I got
x = 6.005 or a negative

so adding 6 to 184 --->1990
