Question
Solve the equation
x1=−19,x2=0,x3=19
Alternative Form
x1≈−4.358899,x2=0,x3≈4.358899
Evaluate
4x3=76x
Add or subtract both sides
4x3−76x=0
Factor the expression
4x(x2−19)=0
Divide both sides
x(x2−19)=0
Separate the equation into 2 possible cases
x=0x2−19=0
Solve the equation
More Steps
Evaluate
x2−19=0
Move the constant to the right-hand side and change its sign
x2=0+19
Removing 0 doesn't change the value,so remove it from the expression
x2=19
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±19
Separate the equation into 2 possible cases
x=19x=−19
x=0x=19x=−19
Solution
x1=−19,x2=0,x3=19
Alternative Form
