Solve the equation
x1=−232,x2=0
Alternative Form
x1≈−0.629961,x2=0
Evaluate
−x2−4x5=0
Factor the expression
−x2(1+4x3)=0
Divide both sides
x2(1+4x3)=0
Separate the equation into 2 possible cases
x2=01+4x3=0
The only way a power can be 0 is when the base equals 0
x=01+4x3=0

Evaluate
1+4x3=0
Move the constant to the right-hand side and change its sign
4x3=0−1
Removing 0 doesn't change the value,so remove it from the expression
4x3=−1
Divide both sides
44x3=4−1
