-2 and -6
Assuming you mean n2 + 11n + 30, the factors are (n + 6)(n + 5).
I assume you mean factors for 4x2+10x+6.(2x+3)(2x+2).
x2+5x+6 = (x+2)(x+3) when factored because 2 and 3 are factors of 6
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
Factors are normally positive and so the factors needed are 6 plus 8 = 14 but not -14
x2 - 5x + 6 = (x - 2)(x - 3)
-6 Check: -6+4-6+8 = 0
Multiply out the factors and then you can check: (x + 2)(x + 3) = x² + 3x + 2x + 6 = x² + 5x + 6 ≠ x² + 3x + 4 Therefore False.
-4x2 + 11x - 6 factors to: (-4x + 3) (x - 2)
The factors of 6 are 1, 2, 3, 6. For them to be common, they need to be compared to another set of factors.
No, as it has two factors, (x - 6)(x + 7)
