Question
Solve the equation
x1=−21,x2=0
Alternative Form
x1=−0.5,x2=0
Evaluate
−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
Divide both sides
22x=2−1
Divide the numbers
x=2−1
Use b−a=−ba=−ba to rewrite the fraction
x=−21
x=0x=−21
