−2x(3x+1)
Show Solution
Find the roots
x1=−31,x2=0
Alternative Form
x1=−0.3˙,x2=0
Evaluate
−6x2−2x
To find the roots of the expression,set the expression equal to 0
−6x2−2x=0

Evaluate
−6x2−2x
Rewrite the expression
−2x×3x−2x
Factor out −2x from the expression
−2x(3x+1)
−2x(3x+1)=0
When the product of factors equals 0,at least one factor is 0
−2x=03x+1=0
Solve the equation for x

Evaluate
−2x=0
Change the signs on both sides of the equation
2x=0
Rewrite the expression
x=0
x=03x+1=0
Solve the equation for x
More Steps
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
Use b−a=−ba=−ba to rewrite the fraction
