✔ 最佳答案
=x^2(x^4-26x^2+25)==x^2(x-25)(x^2-1)=
=x^2(x-5)(x+5)(x-1)(x+1)

x^6 - 26x^4 + 25x²
= x²(x^4 - 26x² + 25)
= x²(x² - 25)(x² - 1)
= x²(x + 5)(x - 5)(x + 1)(x - 1)
= x²(x^4 - 26x² + 25)
= x²(x² - 25)(x² - 1)
= x²(x + 5)(x - 5)(x + 1)(x - 1)

a^2 - b^2 â¡ (a + b)(a - b)
x^6 - 26x^4 + 25x^2
= x^2(x^4 - 26x^2 + 25)
= x^2(x^4 - x^2 - 25x^2 + 25)
= x^2[(x^4 - x^2) - (25x^2 - 25)]
= x^2[x^2(x^2 - 1) - 25(x^2 - 1)]
= x^2(x^2 - 1)(x^2 - 25)
= x^2(x^2 - 1^2)(x^2 - 5^2)
= x^2(x + 1)(x - 1)(x + 5)(x - 5)
x^6 - 26x^4 + 25x^2
= x^2(x^4 - 26x^2 + 25)
= x^2(x^4 - x^2 - 25x^2 + 25)
= x^2[(x^4 - x^2) - (25x^2 - 25)]
= x^2[x^2(x^2 - 1) - 25(x^2 - 1)]
= x^2(x^2 - 1)(x^2 - 25)
= x^2(x^2 - 1^2)(x^2 - 5^2)
= x^2(x + 1)(x - 1)(x + 5)(x - 5)

I've always been fond of "Whoop de doo!' and "Boy Howdy!" myself.
It's always been a factor in my enjoyment.
