To factorize this equation, Let's split the middle term,
-19x can be written as (2x - 21x),
Now re writting the equation,
7x² - 21x + 2x - 6
=> Taking 7x common in first 2 terms, and 2 common in last two terms,
=> 7x(x-3) + 2(x-3)
Now taking (x-3) common,
=> (x-3)[7x+2],
This is the required answer,
So therefore the answer is (x-3)[7x+2],
If you need zeroes of the equation, Let the equation be equal to zero,
Now either x-3 = 0, or 7x +2 = 0,
=> Either x = 3 , or x = -2/7,
So zeroes of equation are 3, -2/7,

Answer:
7x²-19x+6.
7x²-21x+2x+6.
-7x(x+3)+2(x+3)
-7x+2)(x+3)
.so x=2/7.
or x= -3
