Answer:
Therefore, the first polynomial is:
[tex]Z=\frac{1}{2}x^2+\frac{1}{2}\\[/tex]
the second polynomial is:
[tex]Y=\frac{1}{2}x^2-\frac{1}{2}\\[/tex]
Step-by-step explanation:
We assume that: Z is first polynomial and Y is second polynomial.
Therefore, we have
[tex]Z+Y=x^2\\\\Z-Y=1\\\\\implies Z+Y+Z-Y=x^2+1\\\\2Z=x^2+1\\\\Z=\frac{1}{2}x^2+\frac{1}{2}\\[/tex]
now, we get
[tex]\implies Z+Y-Z+Y=x^2-1\\\\2Y=x^2-1\\\\Y=\frac{1}{2}x^2 -\frac{1}{2}[/tex]
Therefore, the first polynomial is:
[tex]Z=\frac{1}{2}x^2+\frac{1}{2}\\[/tex]
the second polynomial is:
[tex]Y=\frac{1}{2}x^2-\frac{1}{2}\\[/tex]
We will see that the polynomials are:
- p(x) = (1/2)*x^2 + 1/2
- q(x) = (1/2)*x^2 - 1/2
How to find the polynomials?
We want to get two polynomials p(x) and q(x) such that:
- p(x) + q(x) = x^2
- p(x) - q(x) = 1
Because of the things that appear on the sum and difference we can assume that:
- p(x) = a*x^2 + b
- q(x) = c*x^2 + d
Then when we rewrite the equations above we find that:
p(x) + q(x) = (a + c)*x^2 + (b + d) = x^2
From this we get:
a + c = 1
b + d = 0
The other equation is:
p(x) - q(x) = (a - c)*x^2 + (b - d) = 1
Then we have:
a - c = 0
b - d = 1
Now we just need to find solutions of:
- a + c = 1
- b + d = 0
- a - c = 0
- b - d = 1
From the second equation we can get:
b = -d
Then we replace that in the fourth equation:
b - d = 1
b + b = 1
2*b = 1
b = 1/2
Then:
d = -b = -1/2
Now two equations remain:
a + c = 1
a - c = 0
From the second we get:
a = c
Replacing that in the first one:
a + c = 1
a + a = 1
2a = 1
a = 1/2 = c
Then the polynomials are:
- p(x) = (1/2)*x^2 + 1/2
- q(x) = (1/2)*x^2 - 1/2
