Which of the binomials below is a factor of this trinomial?
15х2 + 13х- 20
а. 3x+5
в. 3x-4
с. 3х - 5
d. 3х + 4

A. 3x+5

Step-by-step explanation:

To factor this equation, i will factor by grouping

(15x²-12x) + (25x - 20)

Then ill factor a 3x from (15x²-12x)

3x(5x-4x)

and factor a 5 from (25x - 20)

5(5x - 4)

So the equation can be written as:

3x(5x-4x) + 5(5x - 4)

if we factor a 5x-4 from both terms, the equation is

(5x-4)(3x+5)

So 3x + 5 is your answer.

In this question, to find the answer we would need to factor the trinomial.

We are factoring

Factor:

When you're done factoring, you would notice that you see the common binomial of 3x + 5.

So the factor of the trinomial would be 3x + 5

This means that answer choice А. 3x + 5
