Hey dhlab. What have you tried? Hint: Try using the rational roots theorem to see if you can get a possibility of a rational root first off.

Could you please guide further as to how do we use quadratic formula for a bi-quadratic equation. thanks Originally Posted by Prove It Write it as with , which can be solved using the Quartic Formula. Then solve for ...
I didn't say Quadratic Formula, I said Quartic Formula. I suggest you read this:

What do you mean by saying " ? It certainly is equal to 0 or some values of x. (You are correct that is never 0 and that is all you need to show that the sum is not 0.)
by using x = y = B/4 we get ( y+1)^4 - 4 ( y+1)^3 + 8(y+1)^2 + 3 = 0 y^4+2y^2 +8y+8=0 (y^2+1)^2 = 8y -7 How do we proceed from hereonward
