Answer: 1) Let's simplify step-by-step.
x22(x+y)−y2
Distribute:
=(x22)(x)+(x22)(y)+−y2
=x23+x22y+−y2
Answer:
=x23+x22y−y2
2)Let's simplify step-by-step.
x4+x2y2+y4
There are no like terms.
Answer:
=x4+x2y2+y4
Answer:
Radius r = ±√52
Coordinates of center =
Step-by-step explanation:
Points to remember
Equation of a circle passing through the point (x1, y1) and radius r is given by
(x - x1)² + (y - y1)² = r ²
<u>To find the radius and coordinates of center</u>
It is given that an equation of circle,
(x - 4)² + (y + 6)² = 52
Compare two equations,
we get r ² = 52
r = ±√52
(x - x1)² = (x - 4)² then x1 = 4
(y - y1)² = (y + 6)² then y1 = -6
Coordinates of center = (4, -6)
