Answer:
Step-by-step explanation:
Here, we add up two polynomials shown.
The polynomials are:
In order to add up the 2 polynomials shown, we have to see the "like terms" and add them up.
We add up the "" terms and the constant (number) terms. There is one term with "m", so we leave it like that. Let's add up. Shown below:\
This is the sum of the 2 polynomials shown:
Answer:
(x-2)²/100 + (y+3)²/64 = 1
Step-by-step explanation:
C (2,-3): h=2 k=-3
semimajor axis (CV): a=12-2=10
center-foci: c=8-2=6
semi minor axis: b² = a²-c²= 100 - 36 = 64
equation: (x-h)²/a² + (y-k)²/b² = 1
(x-2)²/100 + (y+3)²/64 = 1
