Answer:

...,............................

Answer 2

Answer:

Sten a similar manner, we can factor some trinomials of degree 4 by treating x4 as (x2)2m and factoring to (a1x2 + c1)(a2x2 + c2), (a1x2 - c1)(a2x2 - c2), or (a1x2 - c1)(a2x2 + c2). For example, we factor x4 +6x2 + 5 as (x2)2 +6(x2) + 5: x4 +6x2 +5 = (x2)2 +6(x2) + 5 = (x2 +5)(x2 + 1).

Some of these expressions can be factored further; if one of the resulting binomials is a difference of squares, for example, factor that binomial:

x4 -4x2 -45 = (x2)2 -4(x2) - 45 = (x2 -9)(x2 +5) = (x + 3)(x - 3)(x2 + 5).
