A. 3x+5

Step-by-step explanation:

To factor this equation, i will factor by grouping

(15xยฒ-12x) + (25x - 20)

Then ill factor a 3x from (15xยฒ-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.

\large\boxed{A).\,3x+5}

Step-by-step explanation:

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

We are factoring 15x^2 + 13x- 20

Factor:

15x^2 + 13x- 20\\\\15x^2+25x-12x-20=0\\\\\text{Factor}\\\\5x(3x+5)-4(3x+5)

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 ะ. 3x + 5

I hope this helped you out.Good luck on your academics.Have a fantastic day!
