Tính: (x^6 – 2x^4 + x^2 ) : ( –2x^2)
Giải thích
x6 – 2x4 + x2) : (–2x2)
= x6 : (–2x2) – 2x4 : (–2x2) + x2 : (–2x2)
= \(\frac{{ - 1}}{2}\). x6 – 2 + x4 – 2 – \(\frac{1}{2}\)
= \(\frac{{ - 1}}{2}\)x4 + x2 – \(\frac{1}{2}\)
x6 – 2x4 + x2) : (–2x2)
= x6 : (–2x2) – 2x4 : (–2x2) + x2 : (–2x2)
= \(\frac{{ - 1}}{2}\). x6 – 2 + x4 – 2 – \(\frac{1}{2}\)
= \(\frac{{ - 1}}{2}\)x4 + x2 – \(\frac{1}{2}\)
