Question
Solve the equation
d=0
Evaluate
−6d=73d3
Add or subtract both sides
−6d−73d3=0
Factor the expression
−d(6+73d2)=0
Divide both sides
d(6+73d2)=0
Separate the equation into 2 possible cases
d=06+73d2=0
Solve the equation
More Steps

Evaluate
6+73d2=0
Move the constant to the right-hand side and change its sign
73d2=0−6
Removing 0 doesn't change the value,so remove it from the expression
73d2=−6
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 d
d∈/R
d=0d∈/R
Solution
d=0
