Melissa purchased a new car. The car had a list price of $20,540. Melissa made a down payment of $3,900 and financed the rest, paying 8.6% interest compounded monthly over a payment period of 5 years. If Melissa also had to pay 8.25% sales tax, a $995 vehicle registration fee, and a $57 documentation fee, what is her monthly payment?

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
