Use the method of completing the square to transform the quadratic equation into the equation form (x – p)^2 = q.

x⁴ - 8x² = 0
x⁴ - 8x² + 16 = 0 + 16
x⁴ - 4x² - 4x² + 16 = 16
x²(x²) - x²(4) - 4(x²) + 4(4) = 16
x²(x² - 4) - 4(x² - 4) = 16
(x² - 4)(x² - 4) = 16
(x² - 4)² = 16

The answer is B.

Find the percent of increase from 1.5 inches to 6 inches.

Komok [63]

Well, from 1.5 to 6 is a 4.5 difference.

now, if we take 1.5 to be the 100%, what is 4.5 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1.5&100\\
4.5&p
\end{array}\implies \cfrac{1.5}{4.5}=\cfrac{100}{p}\implies p=\cfrac{4.5\cdot 100}{1.5}$

To solve this, you have to use the unit rate (20/5=4), and you also have to convert meters to kilometers.
