Answer:
f(x) = x² - 6x + 14
Step-by-step explanation:
Standard form is ax² + bx + c = 0 or f(x) = ax² + bx + c
So we are going to expand the equation and combine like terms:
f(x) = (x - 3)² + 5
f(x) = x² - 3x - 3x + 9 + 5
f(x) = x² - 6x + 9 + 5
f(x) = x² - 6x + 14
Step one: Subtract $15 - $5.50 = $9.50
<span>Step two: divide $9.50 ÷ $15 = .633 (rounded) </span>
<span>Step three: Multiply .633 * 100 to change it to a percent. It becomes 63.3% (rounded) </span>
<span>The decrease is 63.33% </span>
<span>Proof: $15 * .63333 = $9.50 </span>
<span>Subtract $15 - $9.50 = $5.50

Step-by-step explanation:
Answer:
(x + 8)(x - 9)
Step-by-step explanation:
(x+8)(x-9)
= x² - 9x + 8x - 72
= x² - x - 72
Then
The factorization of x² - x - 72 is (x+8)(x-9)
