<em />Here's a little explanation as to how we got those answers. A power is an exponent given to a number indicating that the base number is being multiplied by itself that many times. Here's an example:
<em>
</em>
<em />The 4 is our base number and it is given the exponent 3, so we would read this expression like so, " Four to the third power". That third power means that 4 is being multiplied by itself 3 times. so, it would look something like this:
<em>
4 x 4 x 4
16 x 4
64

Answer:
74.958 lb-in
Step-by-step explanation:
We are given that
Natural length of spring=l=6 in
After stretching, the length of spring=8.3 in
Weight=W=9 lb
Extension in the sprig=8.3-6=2.3 in
By hook's law

Using the formula


Extension in the spring when the length of spring after stretching to 12.2 in=12.2-6=6.2 in
Work done, W=
![W=[\frac{3.9x^2}{2}]^{6.2}_{0}](https://tex.z-dn.net/?f=W%3D%5B%5Cfrac%7B3.9x%5E2%7D%7B2%7D%5D%5E%7B6.2%7D_%7B0%7D)


The new polynomial identity is 2(x² + 2xy + y²)
Given,
The polynomial identities
Column A Column B
(x − y) (x2 + 2xy + y2)
(x + y) (x2 − 2xy + y2)
(y + x) (ax + b)
(y − x) (cy + d)
We have to square an identity from column A and add it with any one identity from column B.
So,
Lets take (x + y)
(x + y)² = x² + 2xy + y²
We can add this identity with x² + 2xy + y² in column B.
That is,
x² + 2xy + y² + x² + 2xy + y²
= 2x² + 4xy +2 y²
= 2(x² + 2xy + y²)
That is,
The new polynomial identity is 2(x² + 2xy + y²)
