The answer is C.
Explanation:
(First, make sure the to finish solving the quadratic equation)
x^2 + 2x - 16 = 12x
x^2 - 10x - 16 = 0
(a, b and c are the coefficients of x^2, x and the constant respectively)
a = 1, b = -10, c = -16
(We can substitute this into the quadratic equation. +- means + or -)
x = [- b +- sqrt(b^2 - 4ac)]/2a
= [- (-10) +- sqrt(100 + 64)]/2
= [10 +- sqrt(164)]/2
(So C is the answer)

To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right.
14^(7x) = 17^(-8-x)
Take the log of both sides:
7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.
Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17
Then:
-8*log 17
x= -------------------------- (answer)
7*log 14 + log 17
