Answer:
![\boxed{\sf \ \ \ 3x^3-9x^2-30x=3x(x-5)(x+2) \ \ \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20%5C%20%5C%20%5C%203x%5E3-9x%5E2-30x%3D3x%28x-5%29%28x%2B2%29%20%5C%20%5C%20%5C%20%7D)
Step-by-step explanation:
hello
step 1 - put 3x in factor
![3x^3-9x^2-30x=3x(x^2-3x-10)](https://tex.z-dn.net/?f=3x%5E3-9x%5E2-30x%3D3x%28x%5E2-3x-10%29)
step 2 - factorise the quadratic form
product of zeros are -10 and the sum is 3, the roots are 5 and -2, as below
![x^2-3x-10=x^2+2x-5x-10=x(x+2)-5(x+2)=(x-5)(x+2)](https://tex.z-dn.net/?f=x%5E2-3x-10%3Dx%5E2%2B2x-5x-10%3Dx%28x%2B2%29-5%28x%2B2%29%3D%28x-5%29%28x%2B2%29)
so the answer is
![3x^3-9x^2-30x=3x(x-5)(x+2)](https://tex.z-dn.net/?f=3x%5E3-9x%5E2-30x%3D3x%28x-5%29%28x%2B2%29)
hope this helps
