Hello from MrBillDoesMath!

Answer:

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


Discussion:


Let u = x^4, then

x^8 - 3x^4 + 2

= u^2 - 3u + 2

= (u -2) ( u -1)

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



Thank you,

MrB

Answer:  (x - 1)(x + 1)(x² + 1)(x⁴ - 2)

<u>Step-by-step explanation:</u>

Given: x⁸ - 3x⁴ + 2

Let u = x⁴

then we get: u² - 3u + 2

Factor: (u - 1)(u - 2)

Substitute (replace u): (x⁴ - 1)(x⁴ - 2)    <em>repeat these steps for x⁴ - 1</em>  

***********************************************

x⁴ - 1

Let u = x²

then we get: u² - 1

Factor: (u - 1)(u + 1)

Substitute (replace u): (x² - 1)(x² + 1)   <em>       factor x² - 1</em>

<em>*</em>***********************************************

x² - 1

Factor: (x - 1)(x + 1)


Next, put all the factors together.  <em>You should have 8 x's (degree of 8)</em>

(x⁴ - 2)(x² + 1) (x - 1)(x + 1)

Simplify the following polynomial and write the answer in standard form. (9-2x^3+5^2-4x+5) - (-2x^3+2x-3)
pogonyaev
If I am reading the question correctly it would come out to -6x+42  First do all the addition and squaring, then factor in that negative.  You come out to -2x^3 +2x^3-4x-2x+25+5+9+3.  The x^3's cancel, the -x's add to -6x, then all that other adds to 42.
