Step-by-step explanation:
<span>If you're aware of the binomial theorem, you have that:
</span>


The fourth term is then the case

, from which:
Brackets & Non Brackets
Step-by-step explanation:
You could sort them into equations with brackets and equations without brackets
if they're both even, divide by two. rational numbers presume reduced fractions. Dividing rational numbers. If two numbers you want to divide, flip the 2nd and multiply.
Answer:

Step-by-step explanation:
In this problem we have the equation of the following quadratic equation and we want to solve it using the method of square completion:

The steps are shown below:
For any equation of the form: 
1. If the coefficient a is different from 1, then take a as a common factor.
In this case
. Then we go directly to step 2
2. Take the coefficient b that accompanies the variable x. In this case the coefficient is 6. Then, divide by 2 and the result squared it.
We have:


3. Add the term obtained in the previous step on both sides of equality

4. Factor the resulting expression, and you will get:

Now solve the equation:
Note that the term
is always > 0 therefore it can not be equal to -32.
The equation has no solution in real numbers.
In the same way we can find the complex roots:
