Explain the relationship between the polynomial identities: x^2 − 1 = (x +1)(x − 1) and x^2 − a^2 =(x − a)(x +a).

Bess [88]

Answer:

So these two equation can be related by identity $x^2-a^2=(x+a)(x-a)$

Step-by-step explanation:

We have given equation $x^2-1=(x+1)(x-1)$

And $x^2-a^2=(x+a)(x-a)$

We know the algebraic identity $a^2-b^2=(a+b)(a-b)$

From this identity

$x^2-1$ can be written as (x+1) (x-1)

And using same identity $x^2-a^2$ can be written as $(x-a)(x-b)$

So these two equation can be related by identity $x^2-a^2=(x+a)(x-a)$

The statements with their relation to 0 are:

Oliver owes his sister $27. $\to$ -27
A building is 38 feet tall. $\to$ 27
Erica jumped 2.7 feet above ground. $\to$ 2.7
The scuba diver was 38 feet below sea level. $\to$ -38
The basement is 8.3 feet below ground. $\to$ -8.3

Statements that represent positions above the sea level are illustrated using the positive sign, while positions below the sea level are represented using the negative sign.

The above highlights imply that the following statements would be represented with positive sign:

A building is 38 feet tall.
Erica jumped 2.7 feet above ground.

This is so, because height and positions above the ground are above the sea level

Also, the following statements would be represented with negative sign:

Oliver owes his sister $27. $\to$ -27
The scuba diver was 38 feet below sea level. $\to$ -38
The basement is 8.3 feet below ground. $\to$ -8.3

This is so, because debt and positions below the ground are below the sea level
