Answer:

$2(x + 15)(x-1)$

Step-by-step explanation:

In order to factor, we take out common terms.

$6x^{2} + 28x -10$
The biggest common term we can factor out is 2:
$2(3x^{2} +14-5)$
Now we factor the area in parentheses into 2 binomials. To do this we need 2 numbers that multiply to be -15 and add to be 14. Theses numbers are 15 and -1.
$2(x + 15)(x-1)$
