Answer to Problem 42E

  y=(4x)+200x2+48012 and y=(4x)200x2+48012.

Explanation of Solution

Given:

  9x2+4xy+6y2=20.

Concept used:

First solve the given equation for y , it can write the equation in the form of ay2+by+c=0 .

  y=b±b24ac2a .

Graph of an equation can be plot using the Desmos graphing calculator.

Calculation:

Consider the equation of the conic:

  9x2+4xy+6y2=20.

First solve the given equation for y , it can write the equation in the form of ay2+by+c=0 .

  6y2+4xy+(9x220)=0.

Now use the quadratic formula to solve for y :

  y=(4x)+(4x)24.6(9x220)2.6.(4x)±200x2+48012.

The two roots of the y are:

  y=(4x)+200x2+48012 and y=(4x)200x2+48012.

The graph of the equation 9x2+4xy+6y2=20. is:

Hence, the new equation so form is

  y=(4x)+200x2+48012 and y=(4x)200x2+48012. .
