Answer:

You cannot solve by factoring

Step-by-step 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
