Answer:

(x-2)^2=36

Step-by-step explanation:

In order to figure out what number should go in the blank within the parentheses, we use the formula \frac{b}{2} , where b is the coefficient of the x term. In this case, b = -4. So, the number in the parentheses blank is: \frac{-4}{2} =-2.

Now, on the left, our parenthetical expression is: (x-2)^2. However, we're not done. The top and bottom equations still need to equal each other. Let's see if they are equal by expanding the (x-2)^2: (x-2)^2=x^2-4x+4. Clearly, they're not the same because the top equation has a -32, whereas the bottom one has +4. So, in order to make these the same, we need to add or subtract something to the right side of the bottom equation.

What will make the left side have -32? If the right side has + 36: x^2-4x+4=36. We can check this by subtracting 36 from both sides: x^2-4x+4-36=36-36  ⇒  x^2-4x-32=0 ... and they match.

So, our final answer is: (x-2)^2=36

Hope this helps!

Answer:

-2; 36

Step-by-step explanation:

x² - 4x - 32 = 0

x² - 2(x)(2) + 2² - 2² - 32 = 0

(x - 2)² - 4 - 32 = 0

(x - 2)² - 36 = 0

(x - 2)² = 36

Which number is the solution of n/3= -12?<br><br> A: -36 <br> B: -4<br> C: 4<br> D: 36
faust18 [17]
N/3= -12.
You want to get "N" by itself. On one side of the equation, with no other number. To do this, we do the opposite of what we have next to the letter "N"
In this case, N is being divided by 3, and the opposite of dividing is multiplying.
So you need to multiply both sides by 3.
The 3's on the left side cancel out, leaving N by itself.
Now you have N= -12 * 3
-12 * 3 = -36

So N = -36
