The binomial factor of the equation
is 3x-8.
<h3>What is a binomial factor?</h3>
The algebraic expression which contains only two terms is called binomial. It is a two-term polynomial. Also, it is called a sum or difference between two or more monomials.
Factoring binomials means breaking down a binomial expression into its simplest form.
Binomials are algebraic expressions with two terms.
The given binomial is;

The binomial is determined in the following steps given below.

Hence, the binomial factor of the equation
is 3x-8.

3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.
4.50x+3x=1140
You will add 4.50 and 3 together to get 7.5.
your equation is now...
7.50x=1140
you divide by 7.5 and get 152. so x= 152.
I am stuck now.

so in short, the only factoring doable to it, without any complex factors, is that of taking the common factor of 2x.
now, the trinomial of 2x²+x+1, will not give us any "real roots", just complex or "imaginary" ones.
if you have already covered the quadratic formula, you could test with that, or you can also check that trinomial's discriminant, and notice that it will give you a negative value.
