Step-by-step explanation:
= 5x^2 – 13x – 6
= 5x^2 + 2x − 15x − 6
Group the first two terms and the last two terms.
= (5x^2 + 2x) − 15x - 6
Factor out the greatest common factor (GCF) from each group.
= x (5x + 2) − 3(5x + 2)
Factor the polynomial by factoring out the greatest common factor, 5x + 2.
= (5x + 2)(x - 3)
