2x2+13x+15 = (2x+3)(x+5)
4x4 + 1 = (2x2 - 2x + 1)(2x2 + 2x + 1)
Doesn't factor evenly, use quadratic
2x2 - 5x + 12 does not factor. 2x2 - 5x - 12 factors into (2x + 3)(x - 4) 2x2 + 5x - 12 factors into (2x - 3)(x + 4)
(2x + 1)(x + 4)
(2x + 1)(x + 3)
(2x+4)(x+1)
No. You'd have to use the ABC-formula
The expression cannot be factorised.
2(x + 6)(x + 3)
2(x^2 +2x + 3)
The factorisation is as follows: 2x2 + 7x - 9 = (x - 1)(2x + 9).
