There is no solution!

Step-by-step explanation:

No Solution.

Step-by-step explanation:

81x2+9y2-648x-54y+648=0

No solutions found

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 81•(x2))+32y2)-648x)-54y)+648  = 0

Step  2  :

Equation at the end of step  2  :

 (((34x2 +  32y2) -  648x) -  54y) +  648  = 0

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  81x2 - 648x + 9y2 - 54y + 648  =

 9 • (9x2 - 72x + y2 - 6y + 72)

Equation at the end of step  4  :

 9 • (9x2 - 72x + y2 - 6y + 72)  = 0

Step  5  :

Equations which are never true :

5.1      Solve :    9   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2     Solve   9x2-72x+y2-6y+72  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.
