Solution
−6x2−3x−3+x−1−3
Show Solution

Find the roots
x1=0,x2=21
Alternative Form
x1=0,x2=0.5
Evaluate
x−13x2−6x3
To find the roots of the expression,set the expression equal to 0
x−13x2−6x3=0
Find the domain
More Steps

Evaluate
x−1=0
Move the constant to the right side
x=0+1
Removing 0 doesn't change the value,so remove it from the expression
x=1
x−13x2−6x3=0,x=1
Calculate
x−13x2−6x3=0
Cross multiply
3x2−6x3=(x−1)×0
Simplify the equation
3x2−6x3=0
Factor the expression
3x2(1−2x)=0
Divide both sides
x2(1−2x)=0
Separate the equation into 2 possible cases
x2=01−2x=0
The only way a power can be 0 is when the base equals 0
x=01−2x=0
Solve the equation
More Steps

Evaluate
1−2x=0
Move the constant to the right-hand side and change its sign
−2x=0−1
Removing 0 doesn't change the value,so remove it from the expression
−2x=−1
Change the signs on both sides of the equation
2x=1
Divide both sides
22x=21
Divide the numbers
x=21
x=0x=21
Check if the solution is in the defined range
x=0x=21,x=1
Find the intersection of the solution and the defined range
x=0x=21
Solution
x1=0,x2=21
