Sinea thinks that the fully factored form of the expression (x^4-1) is (x^2-1)(x^2+1). Is she correct? Explain.
iVinArrow [24]

Answer:

No. See below.

Step-by-step explanation:

( {x}^{4}  - 1)

Use the following formula (Difference of Two Squares)

{x}^{2}  -  {y}^{2}  = (x + y)(x  - y)

( {x}^{4}  - 1) = ( {x}^{2}  + 1)( {x}^{2}  - 1)

We are not done yet. As we can still factor the expression which is x²-1 by using the same formula.

( {x}^{2}  + 1)(x + 1)(x - 1)

This is the fully factored form.

I need help with this question, I need to find the slope and figure out if it’s a negative,positive,zero, or undefined
DENIUS [597]
Well I would say that you would probably want to look at the chart and add the points together on that X to Y Coordinate chart. If it slopes into lower numbers it’s negative. If it goes higher in numbers it’s positive. Then if it’s to 0 then it’s zero. I can’t remember what undefined is

The temperature rose, which means it increased. An increase is a positive value, so add a plus sign in front of the number: +4

A decrease is a negative value, so add a negative sign in front of the value: -19
