Question
Solve the equation
k=0
Evaluate
41k=3(−41k3)
Multiply the numbers
More Steps

Evaluate
3(−41)
Multiplying or dividing an odd number of negative terms equals a negative
−3×41
Multiply the numbers
−43
41k=−43k3
Add or subtract both sides
41k−(−43k3)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
41k+43k3=0
Factor the expression
k(41+43k2)=0
Separate the equation into 2 possible cases
k=041+43k2=0
Solve the equation
More Steps

Evaluate
41+43k2=0
Move the constant to the right-hand side and change its sign
43k2=0−41
Removing 0 doesn't change the value,so remove it from the expression
43k2=−41
Since the left-hand side is always positive or 0,and the right-hand side is always negative,the statement is false for any value of k
k∈/R
k=0k∈/R
Solution
k=0
