(2x - 1)(x + 7)
If that's plus 36, it factors to (x - 9)(x - 4) If it's minus 36, it gets ugly in a hurry.
6(13x + 6)
(x + 9)(x + 4)
(x + 9)(x + 4)
It is x^2 -13x +12 = (x-1)(x-12) when factored
(x-4)
6x^2 -13x+6 = (3x-2)(2x-3) when factorized
(x - 3)(2x - 7)
-6 = 3 x -2 13 = 5 x 3 - 2 → 5x² + 13x - 6 = (5x - 2)(x + 3)
(13x^2 - 4y)(2x^2 - 5y)
(2x - 1)(x + 7)
13X squared + 7X + 12
It is (2x-5)(x-4) when factored
x^2 - 13x + 36 = 0 Factor: (X-9)(X-4) = 0 X = 9 X = 4
If that's plus 36, it factors to (x - 9)(x - 4) If it's minus 36, it gets ugly in a hurry.
(13x + 39)(x + 2) * * * * * Don't you think it might, instead, be (13x - 39)(x - 2)? Multiply it out, and see!
