the answer is (3x+4)(x-5)

Answer:

2 and 5

Step-by-step explanation:

Use the sum-product pattern

3x^{2}{\color{#c92786}{-11x}}-20

3x^{2}+{\color{#c92786}{4x}}{\color{#c92786}{-15x}}-20

2

Common factor from the two pairs

3x^{2}+4x-15x-20

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

3

Rewrite in factored form

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

(x-5)(3x+4)
