Answer to Problem 4E

Since D<0 , the given curve represents a ellipse.

Explanation of Solution

Given:

  2x215xy+2y2+x+y=0

Formula Used:

The formula used for discriminant is

  B24AC

Calculation:

Given the following equation:

  2x215xy+2y2+x+y=0

Comparing with the standard equation for a Quadratic Curve,

  Ax2+Bxy+Cy2+Dx+Ey+F=0

Thus,

  A=2, B=15, C=2

Now, discriminant D=B24AC

  =(15)24(2)(2)=1

Since D<0 , the given curve represents a ellipse.

Conclusion:

Since D<0 , the given curve represents a ellipse.
