Question

(x^2+2)^2-4(x^2+2)+4

Answer 1

x^4+x6+4-4x^2-8+4=6x+x^4-4x^2

Answer 2

Ну вот так вот, если уравнение не равно нулю

Answer 3

Let's simplify the expression:

Starting with $(x^2+2)^2$, we can expand it using the square of a binomial formula: $(x^2+2)^2 = (x^2)^2 + 2\cdot x^2 \cdot 2 + 2^2 = x^4 + 4x^2 + 4$.

Now, substituting this back into the original expression:

$(x^2+2)^2 - 4(x^2+2) + 4$ $= (x^4 + 4x^2 + 4) - 4(x^2+2) + 4$ $= x^4 + 4x^2 + 4 - 4x^2 - 8 + 4$ $= x^4 - 4x^2$.

Therefore, the simplified expression is $x^4 - 4x^2$.
