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)

Answer:
Now, derive it from the calculations
Step-by-step explanation:
Net income = 100% = N120,000
therefore
1. Food
40%/100% = 2/5 of N120,000
= N48,000
2.Housing
30%/100% = 3/10 of N120,000
= N36,000
3. Savings
20%/100% = 2/10 (or 1/5) of N120,000
= N24,000
4. Miscellaneous
10%/100% = 1/10 of N120,000
= N 12,000

1 2/5 - (-3/5)
First, we're going to convert 1 2/5 into an improper fraction.
1 2/5 = 7/5
7/5 - (-3/5)
Subtracting a negative is the same as adding, so the problem will look like:
7/5 + 3/5
The denominators are the same, so we just add the numerators.
The answer is 10/5, or 2.
