-(x + 5)(x + 6)
(x + 9)(x + 2)
13x(x+3x)
prime factorization of 89: 1 and 89
8a(5a2-1)
We can't answer that without knowing what the polynomial is.
90
Several characters missing but I will hazard a gues and factorise 121x2 - 22x + 1 as (11x - 1)2
12
(x + 2)(3x + 1)
Start by looking for a common factor. Separate this factor, then factor the remaining polynomial.
-(x + 5)(x + 6)
(x + 9)(x + 2)
13x(x+3x)
5(x - 5)(x - 2)
Step 1: 2x.(x2 - 3x - 28) Step 2: 2x.(x - 7)(x + 4)
x3 - 7x2 + 6x =x (x2 - 7x + 6) =x (x - 6) (x - 1)
