Answer: 15x² + 2x + 4

x = -2/3, 0, 1/2

Step-by-step explanation:

5x(3x + 2) - 4(2x - 1)

First, distribute:

15x² + 10x - 8x + 4

Combine like terms:

15x² + 2x + 4

This is your polynomial!

If you needed to solve for x, take your original factored polynomial and set each term equal to 0:

5x(3x + 2) - 4(2x - 1)

5x = 0

x = 0

3x + 2 = 0

3x = -2

x = -2/3

-4 = 0

No solution

2x - 1 = 0

2x = 1

x = 1/2

x = -2/3, 0, 1/2

Hope this helps!

Ricky Bobby wants to buy a new automobile for $55,000 in 8 years. How much money must Ricky's original investment be if he makes

laila [671]

Answer:

PV= $40,279.36

Step-by-step explanation:

Giving the following information:

Number of periods= 8*12= 96 months

Interest rate= 0.039/12= 0.00325

Future value (PV)= $55,000

To calculate the initial investment, we need to use the following formula:

PV= FV/(1+i)^n

PV= 55,000 / (1.00325^96)

PV= $40,279.36
