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
