(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6

Question:</h2>
1) It's February and you go to the store to buy some food for your pets. You have a Great
Dane and a Savannah cat. The Dane eats 3 times as much as your cat so his food
cost $60 for the big bag and he eats that in one week. The Savannah cats food cost
$15 a bag and it lasts him one week as well. You are there to buy food for the month
and have no more than $300 total to spend. Can you afford a month's worth of food?
a) If you bought the cat 6 weeks worth of food, how many weeks worth can you
buy your Great Dane?
<h2>
Answer: Yes you can afford </h2><h3>

During an emergency exercise, a submarine dives 37 ft, rises 16 ft, and
then dives 18 ft. The net change in the submarine's position = - 37 + 16 - 18
Net change is the difference between a security's closing price for a given trading period and its closing price for the current trading session. The term "net change" for stock prices often refers to a daily time frame, therefore the net change for the specific day in question might be either positive or negative.
Therefore, the net change = -39 ft.
What is a net change?
- Net change is the difference between the quantity of a variable at the end state and the starting state.
- For example, start with some number. Add 10 to it, subtract 5 from it, again add 7, then subtract 16.
- The net change will be 10 + 5 + 7 - 16 = 6
- Whatever number you have started with, the result is 6 more.

Answer:
x = - 6 ± 
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ±
( subtract 6 from both sides )
x = - 6 ±
← exact solutions
