Start by looking for a common factor. Separate this factor, then factor the remaining polynomial.
12
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
(11x-1)(11x-1)
13x(x+3x)
-(x + 5)(x + 6)
(x + 9)(x + 2)
5(x - 5)(x - 2)
(x + 5)(x + 2)
It is 6x(2x+5) when factored
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)
