Question
Solve the equation
x=0
Evaluate
7x5=−16x
Add or subtract both sides
7x5−(−16x)=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
7x5+16x=0
Factor the expression
x(7x4+16)=0
Separate the equation into 2 possible cases
x=07x4+16=0
Solve the equation
More Steps
Evaluate
7x4+16=0
Move the constant to the right-hand side and change its sign
7x4=0−16
Removing 0 doesn't change the value,so remove it from the expression
7x4=−16
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 x
x∈/R
x=0x∈/R
Solution
x=0
