You save $8,500.00. Your original plan was to place 40% in a savings account earning a 4.2% APR compounded annually and the rest in a stock plan that decreases 3% in the first year and increases 7.5% in the second year. If you had invested 60% in the savings account and the rest in the stock plan, what is the difference in the total gain compared to the original plan?

step-by-step explanation:

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

d 600 because 15*10*2=300

300+300=600
