Give the solution set for the inequality<br> 7x &lt; 7(x - 2) in interval notation.
eduard

<u>ANSWER:</u>

The solution set for the inequality 7x < 7(x - 2) is null set \varnothing

<u>SOLUTION:</u>

Given, inequality expression is 7x < 7 × (x – 2)

We have to give the solution set for above inequality expression in the interval notation form.

Now, let us solve the inequality expression for x.

Then, 7x < 7 × (x – 2)

7x < 7 × x – 2 × 7

7x < 7x – 14

7x – (7x – 14) < 0

7x – 7x + 14 < 0

0 + 14 < 0

14 < 0  

Which is false, so there exists no solution for x which can satisfy the given equation.

So, the interval solution for given inequality will be null set

Hence, the solution set is \varnothing

How do you factor out the Greatest Common Factor of polynomials?
In-s [12.5K]

Answer:

Step-by-step explanation:

In order to factor out the Greatest Common Factor of polynomials, we first have to find the factors of the given polynomials. There are various methods to do that. Now we will write the steps needed to factor out the Greatest Common Factor of polynomials:

a) Breaking down every term into prime factor form.

b) Then we have to look for factors that appear in every single term in order to get Greatest Common Factor of polynomials

c) Now the Greatest Common Factor is taken out or factored out from every term before parentheses and group the remaining expression inside the parentheses.
