3x2 - 11x - 4 = (x-4)(3 x + 1)
The factors are -1(2x + 1)(3x + 4)
That factors to 3x(3x - 1)
3x squared minus 25x minus 28
They are like terms and can be added together as 11x squared
20x2 - 3x + 10 does not have any real factors.
3x2 - 11x - 4 = 0(3x + 1)(x - 4)x = -1/3 and 4
That factors to (x - 3)(x + 6)
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
If you mean: (3x+1) and (2x+3) are factors of 6xsquared+11x+3 then yes they are
(x-3)(3x+1)
x(3x - 2)
3x(6x - 1)
