Answer:

You cannot solve by factoring

Step-by-step explanation:

We want to solve [tex]4x^4-6x^2-7=0[/tex] by factoring.

We can rewrite as: [tex]4(x^2)^2-6x^2-7=0[/tex]

So we have a quadratic equation in [tex]x^2[/tex].

We split the middle term to get:

We look for  factors -28 that sum up to -6

This is not possible hence the given equation is not factorable
