Rewrite the expression
−x×3x−x×23
Factor out −x from the expression
−x(3x+23)
−x(3x+23)=0
When the product of factors equals 0,at least one factor is 0
−x=03x+23=0
Solve the equation for x
x=03x+23=0
Solve the equation for x
More Steps

Evaluate
3x+23=0
Move the constant to the right-hand side and change its sign
3x=0−23
Removing 0 doesn't change the value,so remove it from the expression
3x=−23
Divide both sides
33x=3−23
Divide the numbers
x=3−23
Use b−a=−ba=−ba to rewrite the fraction
