Question
Solve the equation
x1=−2,x2=−1
Evaluate
x3+5x2+8x+4=0
Factor the expression
(x+1)(x+2)2=0
Separate the equation into 2 possible cases
x+1=0(x+2)2=0
Solve the equation
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=−1(x+2)2=0
Solve the equation
More Steps
Evaluate
(x+2)2=0
The only way a power can be 0 is when the base equals 0
x+2=0
Move the constant to the right-hand side and change its sign
x=0−2
Removing 0 doesn't change the value,so remove it from the expression
x=−2
x=−1x=−2
Solution
x1=−2,x2=−1
