Solve the equation xsin(x)^4-xsin(x)^2=0

 Exercise

$x\sin\left(x\right)^4-x\sin\left(x\right)^2=0$

 

We need to isolate the dependent variable $x$, we can do that by simultaneously subtracting $-x\sin\left(x\right)^2$ from both sides of the equation

$x\sin\left(x\right)^4-x\sin\left(x\right)^2+x\sin\left(x\right)^2=0+x\sin\left(x\right)^2$

 

Canceling terms on both sides

$x\sin\left(x\right)^4=x\sin\left(x\right)^2$

 

Cancel $x$ from both sides of the equation

$\sin\left(x\right)^4=\sin\left(x\right)^2$

 

If the bases are the same, then the exponents must be equal to each other

$4=2$

 

$4$ is not equal to $2$

false

false
