Answer:
Simplifying
3x² + - 9xy = 0
Reorder the terms :
- 9xy + 3x² = 0
Solving
- 9xy + 3x² = 0
Solving for variable ' x '
Factor out of the Greatest Common Factor
( GCF ), ' 3x '.
3x ( - 3y + x ) = 0
Ignore the factor 3
Subproblem 1
Set the factor ' x ' equal to zero and attempt to solve :
Simplifying
x = 0
Solving
x = 0
Move all terms containing x to the left , all other terms to the right.
Simplifying
x = 0
Subproblem 2
Set the factor ' ( - 3y + x ) ' equal to zero and attempt to solve :
Simplifying
- 3y + x = 0
Reorder the terms :
x + - 3y = 0
Solving
x + - 3y = 0
Move all terms containing x to the left , all other terms to the right.
Add ' 3y ' to each side of the equation.
x + - 3y + 3y = 0 + 3y
Combine like terms - 3y + 3y = 0
x + 0 = 0 + 3y
x = 0 + 3y
Remove the zero :
x = 3y
Simplifying
x = 3y
Solution
x = { 0, 3y }
