Answer:

You cannot solve by factoring

Explanation:

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

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

So we have a quadratic equation in
x^2.

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
