Question

How do you solve `2x^4 = 16x^2`?

Answer 1

set the equation equal to zero and factor

Explanation:

You can either set the equation equal to zero and factor or you can proceed as follows:
divide both sides by 2
divide both sides by x^2
then set the equation = 0

Answer 2

Put both terms to one side of the equation and then factor.

Explanation:

`2x^4 - 16x^2 = 0`

`2x^2(x^2 - 8) = 0`

`x = 0 and +- sqrt(8)`

Hopefully this helps!
