Case Study 1: Casey is preparing to leave for college in the fall. She lives in New York, but will be going to school in California. She is planning on buying a car to get herself there. She wants to buy something reliable, so she is deciding between a new car that will cost $17,000 with 0 miles and a navigation system and a three-year-old car with 7,000 miles and no navigation system for $12,000. She has $10,000 in savings that she will use for the purchase and will take out a loan for the remaining amount.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

where are the choices?

child does not get an education so she can use the molla on junk

i think the correct option is the second option.
