Evaluate
−36x2−12x
Rewrite the expression
−12x×3x−12x
Factor out −12x from the expression
−12x(3x+1)
−12x(3x+1)=0
When the product of factors equals 0,at least one factor is 0
−12x=03x+1=0
Solve the equation for x

Evaluate
3x+1=0
Move the constant to the right-hand side and change its sign
3x=0−1
Removing 0 doesn't change the value,so remove it from the expression
3x=−1
Divide both sides
33x=3−1
Divide the numbers
x=3−1
