Will mark as brainliest. factor the expression 3x^ 3 + 4x^2 - 15x - 20. show your work.

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

x^2(3x+4)-5(3x-4)

(3x+4)(x^2-5)

add 5 subtract 1

step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.
