<u>Corrected Question</u>
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.
Answer:
all reals except 3 & 4
Step-by-step explanation:
recall you cannot have a 0 in the denominator.
any values of x that would produce a 0 in the denominator are excluded from the domain
factor Factors -3, -4
(x-3)(x-4)
x cannot be 3 or 4
