Answer:

n=5

Step-by-step explanation:

<em>Write an equation </em>

<em>The difference of 3 times a number and six </em>

Difference means subtract. Times means multiply. And means add.

So, 3 times a number, n minus 6

3n-6

<em>Is nine </em>

Is means equal

= 9

3n-6=9

<em>Solve </em>

3n-6=9

Add 6 to both sides

3n-6+6=9+6

3n=15

Divide both sides by 3

3n/3=15/3

n=5

Use the following trinomial to answer the questions. x^2-6x-27 When going through the process of determining the factors, the tw
Sauron [17]

Answer:

The factors are 3 and -9

Step-by-step explanation:

The given trinomial is x^2-6x-27.

We need to find two factors. We know that,

3(9) = 27

So,

x^2-6x-27 can be written as :

x^2+3x-9x-27 as two factors add up to get -6 and multiply to get -27.

Hence, the factors are 3 and -9.

Solving quadratic equations is one of the main topics of this unit. Some quadratic equations can be solved with only one method,
Mariana [72]

Hi there!

Many things we do in everyday life have a variety of ways we can go about accomplishing them, but we most often choose the most practical and efficient method.

Efficiency saves time and prevents over-complication, which may lead to errors.

We might need to identify the specifics of the task and its circumstances to be able to determine the most efficient method to do it.

Solving a quadratic equation, we also must think about the most efficient method that can lead us to the correct answer. And doing so, we must identify the circumstances of the equation; Can it be solved by factoring? Is it easy to factor? What form is this quadratic equation in?

For example, let's say we're given the equation (x-1)(x+2)=0. This is an equation in factored form. In these kinds of scenarios, we can <em>easily</em> solve by setting each term equal to 0 (the Zero Product Property). This is the <em>most efficient </em>method:

x-1=0 --> x=1

x+2=0 --> x=-2

I hope this helps!
