Find the hcf of 1+4x2+16x4

To find the highest common factor (HCF) of the given expression 1 + 4x^2 + 16x^4, we need to factorize it.

We can see that the expression is a perfect square trinomial:

1 + 4x^2 + 16x^4 = (1 + 4x^2)^2

Now let's distribute the square:

(1 + 4x^2)(1 + 4x^2) = 1 + 4x^2 + 4x^2 + 16x^4 = 1 + 8x^2 + 16x^4

So the HCF of 1 + 4x^2 + 16x^4 is 1 + 4x^2.

To find the highest common factor (HCF) of the expression 1 + 4x^2 + 16x^4, we need to factorize it. However, this expression cannot be factored further because it does not have any common factors other than 1.

Therefore, the HCF of 1 + 4x^2 + 16x^4 is 1.
