We have been given an equation x^2 +11x=3. We are asked to complete the square for the given equation.

To complete the square for our given equation, we need to add the half the square of x term on both sides.

We can see that coefficient of x term is 11, so we need to add half the square of 11 on both sides.

(\frac{11}{2})^2  

Let us simplify (\frac{11}{2})^2.

\frac{11^2}{2^2}=\frac{121}{4}

Upon adding \frac{121}{4} on both sides, we will get:

x^2 +11x+\frac{121}{4}=3+\frac{121}{4}

Now we will make a common denominator for right side.

x^2 +11x+\frac{121}{4}=\frac{12}{4}+\frac{121}{4}

x^2 +11x+\frac{121}{4}=\frac{133}{4}

Therefore, our equation would be x^2 +11x+\frac{121}{4}=\frac{133}{4}.

Solve. (Enter your answer using interval notation.)<br> |3x + 15| &gt; 21
Katarina [22]

Answer:

(-∞, -12), (2, ∞)

or

(-∞, -12) U (2, ∞)

Step-by-step explanation:

|3x + 15| > 21, |3x + 15| < -21

3x + 15 > 21,  3x + 15 < - 21

     -15    -15         -15     -15

------------------   -------------------

3x > 6               3x < - 36

÷3  ÷3               ÷3     ÷3

------------         ------------------

x > 2                  x < -12

(-∞, -12), (2, ∞)

or

(-∞, -12) U (2, ∞)

I hope this helps!

Compare partial products and regrouping. describe how the methods are alike and different
svetlana [45]
<span><em>Partial product </em>multiplication is the process of multiplying the numbers partially (respectively to ones, tens and hundreds) and adding them together in the end. For example, in order to find the product of 3 8 × 6 we should write that,
1) 3 8
   × 6
  ___
  4 8

2)  3 8
    ×  6
 _____
     4 8
   1 8 0

3) 3 8
    × 6
______
+  4 8
  1 8 0
 ______
 2 2 8

<em>Regrouping </em>is the multiplication process when we add the partial products to the next tens and hundreds and so on without writing them down. For example, in order to find the product of 3 8 × 6 with the help of regrouping, we write that
   4
3 8
× 6
___
228
, where the number 4 above 8 shows the tens of 4 (40), which is going to be added to the tens of the product of 30 times 6. The two processes are the same in a way that you are getting the same result. In the end, it is a multiplication process. The processes differ because of the methods we apply. In partial product multiplication, we break down the number in its ones, tens, hundreds steps and then calculate. However, in regrouping process we consider those steps without breaking them down. </span>
