3x2 - 19x - 14 = 0
3x2 - 21x + 2x - 14 = 0
3x(x - 7) + 2(x - 7) = 0
(x - 7)(3x + 2) = 0
x - 7 = 0 or 3x + 2 = 0
x = 7 or x = -2/3

It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
Factored, that's 5(x2- 20) The solution depends on the value of x.
2
It is (A-1)(A+1) when factored
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
(a - 2b)(2a - b)
It is: (x+5)(x-8) when factored
(2y+1)(y−5)
It is: (x+5)(x-8) when factored
14x squared minus 7x to the 3rd power can be factored to 7x2(2-x).
64-x2 = (8-x)(8+x) when factored
It is: (2x+3)(3x-8) when factored
