6x3 - 27x2 + 3x + 36 = 3 (x - 4) (x + 1) (2x - 3)
2x3
6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.
Rearrange: 4x5 + 6x2 + 6x3 + 9 Group: 2x2 (2x3 + 3) + 3 (2x3 + 3) Simplify to get your answer: (2x2 + 3) (2x3 + 3)
(3x - 1)(2x2 - 2x - 1)
If that's - 94x, the answer is 2(3x - 10)(x2 + 5x + 1)
The answer is 37.
-6x3 + 4x7 - 0.8x2 + x4 - 5x5 = 4x7 - 5x5 + x4 - 6x3 - 0.8x2 = x2 (4x5 - 5x3 + x2 - 6x - 0.8)
