Which of the binomials below is a factor of this trinomial?

[tex]\(8x^2 + 10x - 3\)[/tex]

A. [tex]\(4x + 3\)[/tex]
B. [tex]\(4x - 3\)[/tex]
C. [tex]\(2x + 3\)[/tex]
D. [tex]\(2x - 3\)[/tex]

Sagot :

To determine which of the given binomials is a factor of the trinomial [tex]\(8 x^2 + 10 x - 3\)[/tex], we will first factor the trinomial completely and then compare the result with the provided options.

The trinomial we have is:
[tex]\[ 8 x^2 + 10 x - 3 \][/tex]

After factoring this expression, we get:
[tex]\[ (2x + 3)(4x - 1) \][/tex]

Now let's write down the given binomials:

A. [tex]\(4x + 3\)[/tex]
B. [tex]\(4x - 3\)[/tex]
C. [tex]\(2x + 3\)[/tex]
D. [tex]\(2x - 3\)[/tex]

We compare each of the factors of the trinomial [tex]\((2x + 3)\)[/tex] and [tex]\((4x - 1)\)[/tex] with the given options.

1. [tex]\(2x + 3\)[/tex] matches option C.
2. [tex]\(4x - 1\)[/tex] does not match any of the options provided.

Therefore, the binomial that is a factor of the trinomial [tex]\(8 x^2 + 10 x - 3\)[/tex] is:

[tex]\[ \boxed{2x + 3 \text{ (Option C)}} \][/tex]
