7x^3-35x^2-6x+30

• algebra -

7x^3 - 35x^2 - 6x + 30
Factor 7x^2 from the first two terms and -6 from the last two terms.

Thank you.. SO would it be

(x-5)(x+5)

• algebra -

7x^2(x-5)-6(x-5)...

• algebra -

(x-5)(x+5)
= x^2 - 25. So, that doesn't work.

Doing the factoring I mentioned previously gives:
7x^2(x - 5) - 6(x - 5)
Now there are two terms. The terms have a common factor of (x-5). Using our friendly distributive law we can write:
(7x^2-6)(x-5)
