Answer:
x = 2
x = -3/2 or -1.5
Step-by-step explanation:
For this, I would use the "slip and slide" method. LOL I know the name is cheesy, but that's what my teacher called it!
First, you "slip" the coefficent of the leading term (2) to the constant, and multiply.
The equation becomes:
x² - x - 6(2) = 0
x² - x - 12 = 0
Then, you factor this out by looking at the second and third terms. You're looking for 2 factors of -12 that would add up to -1 ( the coefficent of the second term).
Automatically, think of 3 and 4, because the difference between them is 1.
The factors must be (x-4) and (x+3) because they multiple to -12, and add up to -1.
This step is extremely important! Lol I used to forget it a lot, but make sure you divide the constant in each factor by the original number you "slipped".
It would become (x-(4/2))(x+3/2) = (x-2)(x+3/2)
With (x+3/2), you don't want to leave it as a fraction or decimal. It's equivalent to (2x+3). However, the informal form is easier to identify the value of x.

First : -(-6) will turn into a positive 6
second: -8+6 which equals -2
Josh did not follow the order of operations , he should have done 8x divided by 2 first but instead he did 4x- 8x
The correct solution...
4x-8x / 2
4x -4x
0
The solution should be zero (0)
Hope it helps!
The question is an illustration of perimeters.
The amount of patio to remove to install the pool is 8 feet.
From the question, we have:


The perimeter of the patio is:



A 1ft walkway means that;
1ft would be subtracted from both sides of the patio before installing the pool
So, the perimeter of the patio in terms of the length of the pool is:

Equate both expressions


Divide both sides by 4

Subtract 2 from both sides

So, the perimeter of the pool is:


The amount of patio to remove is:

So, we have:


Hence, 8ft of the patio would be removed to install the pool
