Answer:
x₁ = - 4 + √31
x₂ = - 4 - √31
Step-by-step explanation:
x² + 8x = 15
x² + 8x - 15 = 0
x = [- 8 ± √8² - 4×1×(-15)]/(2×1)
x = (-8 ± 2√31)/2
x₁ = (-8 ± 2√31)/2
x₁ = - 4 + √31
x₂ = - 4 - √31
Annual means yearly so you need to get the rate each year
156/5=31.2
31.2 Dollars every year
31.2/520=.06
.06*100=6% interest rate every year
