(2x - 1)(4x + 1)
It is (A-1)(A+1) when factored
1, -1, 5, -5
Well, honey, factoring x minus 1 is as easy as pie. You simply write it as (x - 1) and call it a day. No need to make a fuss over such a simple little equation.
(x + 1)(x - 8)
(x - 1)(x + 1)
(2x - 1)(2x + 1)
(t + 1)(2t - 3)
(x-3)(3x+1)
The factors are -1(2x + 1)(3x + 4)
(2x - 1)(4x2 + 2x + 1)
(7a - 1)(6a + 1)
