x + 12x + 20 = (x + 10)(x + 2)
It is the same as xsquared+9x+18 and when factored: (x+3)(x+6)
Step 1: 2x.(x2 - 3x - 28) Step 2: 2x.(x - 7)(x + 4)
(pā6q) (p2+6pq+36q2)
We can't answer that without knowing what the polynomial is.
90
12
-(x + 5)(x + 6)
(x + 9)(x + 2)
13x(x+3x)
(11x-1)(11x-1)
5(x - 5)(x - 2)
It is 6x(2x+5) when factored
(x + 5)(x + 2)
If the cubic polynomial you are given does not have an obvious factorization, then you must use synthetic division. I'm sure wikipedia can tell you all about that.
(x + 2)(3x + 1)
