Question

2) (x^4 – 1)^2 – (x^4 + 4) - (x^4 - 6)​

Answer 1

Вроде бы правильно, если что пожалуйста простите

Answer 2

Let's simplify the expression step by step:

1. Expand (x^4 – 1)^2: $(x^4 - 1)^2 = (x^4 - 1) \times (x^4 - 1) = x^8 - 2x^4 + 1$.

2. Expand (x^4 + 4): $x^4 + 4$.

3. Expand (x^4 - 6): $x^4 - 6$.

Now, let's substitute these expressions back into the original expression and simplify further:

$(x^4 - 1)^2 - (x^4 + 4) - (x^4 - 6)$

$= (x^8 - 2x^4 + 1) - (x^4 + 4) - (x^4 - 6)$

$= x^8 - 2x^4 + 1 - x^4 - 4 - x^4 + 6$

$= x^8 - 4x^4 + 3$.

So, the simplified expression is $x^8 - 4x^4 + 3$.
