In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.
Answer:

Using express exponents, you write C=10(50-t^2)
Step-by-step explanation:
To factor the cost polynomial,
, we follow these steps.
Step 1: Determine the greatest common divisor of the terms in the polynomial
The terms in the polynomial are 
The greatest common divisor of
is 10.
Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.
