Verdich [7]

Answer:

The correct answer is M = -200

Step-by-step explanation:

It is given an equation,

M/5 = -40

In this equation there is only one variable .

The variable is M. To find the value of M we have to evaluate the expression.

<u>To find the vale of M</u>

M/5 = -40

By cross multiplying we get,

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.
