Answer:
Step-by-step explanation:
Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients. 4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.
The discriminant (part of the quadratic formula) is b^2 - 4ac. Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.
-b ± √(b^2 - 4ac)
Then the quadratic formula x = ---------------------------
2a
-(-1) ± √17 1 ± √17
takes on the values x = ----------------- = ---------------

Answer:
A = $ 1,987,379.10 + 700,000= $2,687,379.10
Step-by-step explanation:
15% = 0.15 rate per tear
A = P (1+r/n)^nt
A = 700,000 (1+0.015/12)^12*7
A = 700,000 (1+0.0125)^84
A = 700,000 ((0.9875)^84
A = 700,000 (2.839113)
