<u>Let's first move everything, the constants and variables to one side</u>

    x^2-2=2x ⇒ x^2-2x-2=0

<u>The second form is in the general form of the quadratic equation</u>:

 ⇒ ax^2+bx+c = 0

  • a ⇒ 1
  • b ⇒ -2
  • c ⇒ -2

<u>To find the value of x, we can use the quadratic formula:</u>

  ⇒<em> look at the diagram attached</em>

<em />

<em>   </em>x = \frac{-b-\sqrt{b^2-4ac} }{2a} =\frac{2-\sqrt{(-2)^2-4(1)(-2)} }{2*1} =\frac{2-\sqrt{4+8} }{2} =\frac{2-\sqrt{12} }{2} =\frac{2-2\sqrt{3}}{2} =1-\sqrt{3}

  x = \frac{-b+\sqrt{b^2-4ac} }{2a} =\frac{2+\sqrt{(-2)^2-4(1)(-2)} }{2*1} =\frac{2+\sqrt{4+8} }{2} =\frac{2+\sqrt{12} }{2} =\frac{2+2\sqrt{3}}{2} =1+\sqrt{3}

Answer:

Solution 1: 1+1\sqrt{3}

Solution 2: 1-1\sqrt{3}

Step-by-step explanation:

x^2-2=2x

x^2-2x-2=0

Use quadratic equation.

(-b+-\sqrt{b^2-4ac})/2a

(2+-\sqrt{(-2)^2-4*1*-2})/2

(2+-\sqrt{(4+8}))/2

(2+-\sqrt{12})/2

Solution 1: (2+2\sqrt{3})/2=1+1\sqrt{3}

Solution 2: 1-1\sqrt{3}

L'Shonda purchased a container of juice
cupoosta [38]

L'Shonda purchased a container of juice. 80 calories are from carbohydrates.

<u>Solution:</u>

Given that, LShonda purchased a container of juice that contains 200 calories.  

The label says that 40% of the calories are from carbohydrates.  

We have to find how many calories are from carbohydrates?

Now, according to the given information,

<em>Number of calories from carbohydrates = 40% of the total calories of the juice </em>

Then, calories from carbohydrates = 40% of 200 calories

40% can be written in fraction as \frac{40}{100}

\text { Calories from carbohydrates }=\frac{40}{100} \times 200=40 \times 2=80 \text { calories }

Hence, 80 calories are from carbohydrates.

PIT_PIT [208]

Answer:

22, I think

Step-by-step explanation:

You count all the squares on all of the faces.

So you count the two on the top and double it for the bottom, so four

Then, on the sides you have three so you double that and get six

Next, you double the six squares on the other side and get twelve.

Lastly, you add them up!

4 + 6 + 12

Hope this helps!

What are the x-intercepts of the graph of the quadratic function f(x) = 3(x − 1)(x + 3)?
creativ13 [48]

Answer:

-3, 1

Step-by-step explanation:

f(x) = 3(x − 1)(x + 3)

To find the x intercepts, set the equation equal to zero

0 = 3(x − 1)(x + 3)

Using the zero product property

x-1 = 0     x+3 =0

x=1            x=-3
