There is decrease of 35% in the price of silver in the past 6 months.

Solution:

Given that  

Price of silver went from $26.40 a troy ounce down to $17.16 a troy ounce during past 6 months need to represent this decrease in percentage  

Price of silver before 6 months = initial price = $26.40

Price of silver now = current price = $17.16

Difference in price in 6 months = 26.40 – 17.16 = $9.24

Hence there is decrease of 35% in the price of silver in the past 6 months.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

$113.42

i hope that is right.
