Show all work to factor x^4 − 5x^2 + 4 completely.
Mademuasel [1]

Answer:

(x+1) (x-1) (x+2) (x-2)

Step-by-step explanation:

<u>Let u = x^2</u>

= u^2 - 5u + 4

<u>(Factor u^2 - 5u + 4)</u>

= (u-1) (u-4)

<u>Substitute back u = x^2</u>

= (x^2 -1 ) (x^2 - 4)

<u>Factor x^2 - 1 and x^2 -4</u>

= (x+1) (x-1) (x+2) (x-2)

Hope this helped... :)
