Answer:
Step-by-step explanation:
Solution:
x4 -5x2 +4
(x2-4)(x2-1)
(x+2)(x-2)(x+1)(x-1)
Explanation:
In order to factor a trinomial, we find two numbers whose product is ac and whose sum is b.
In the case of x4 -5x2 +4, these numbers would be -4 and -1. We use x2 for each factor in order to account for the x4 and -5x2. A this point, we notice that x2-4 is a difference of squares that factors to (x+2)(x-2) and x2-1 is also a difference of squares that factors to (x+1)(x-1). So our final answer in factored form is (x+2)(x-2)(x+1)(x-1).
