Given that the difference between the roots of the equation

is

.
Recall that the sum of roots of a quadratic equation is given by

.
Let the two roots of the equation be

and

, then

. . . (1)
Also recall that the product of the two roots of a quadratic equation is given by

, thus:

. . . (2)
From (1), we have:

Substituting for alpha into (2), gives:
Answer: 16y² - x²
Step-by-step explanation: The - sign means a difference, so the choices with + signs are eliminated (though 64x² and 9 are squares)
10 is not a square so that one is eliminated (though the y² and the 4x² are squares)
16 is the square of 4, y² is the square of y, and x² is the square. That expression shows a difference of squares.
It is an arithmetic because it is adding 2 to each number.
$18,617.75 is the answer
$87,525-$77,100=$10,425 (the amount over $77,100)
$10,425 x .28=$2,919 (the 28% taxed amount over $77,100)
$2,919+$15,698.75 (the already taxed amount in the chart)=$18,617.75
