13x(x+3x)
(x + 9)(x + 2)
-(x + 5)(x + 6)
prime factorization of 89: 1 and 89
there is no prime factorization of 72 except for 1 and 72
We can't answer that without knowing what the polynomial is.
90
(x - 2)(x2 + 1)
12
Several characters missing but I will hazard a gues and factorise 121x2 - 22x + 1 as (11x - 1)2
(x + 2)(3x + 1)
Start by looking for a common factor. Separate this factor, then factor the remaining polynomial.
13x(x+3x)
(x + 9)(x + 2)
-(x + 5)(x + 6)
5(x - 5)(x - 2)
(x + 5)(x + 2)
