化简 ((50x^4)/(25*x^2))-12x^2

解答

化简

(\frac{50 x ^{4}}{25 \cdot x ^{2}}) - 12 x^{2}

- 10 x^{2}

求解步骤

(\frac{50 x ^{4}}{25 x ^{2}}) - 12 x^{2}

使用法则:

(a) = a

(\frac{50 x ^{4}}{25 x ^{2}}) = \frac{50 x ^{4}}{25 x ^{2}}

= \frac{50 x ^{4}}{25 x ^{2}} - 12 x^{2}

消掉

\frac{50 x ^{4}}{25 x ^{2}} : 2 x^{2}

= 2 x^{2} - 12 x^{2}

s im pl i f y 9 - 9 x^{9} + 9

f a c t or 25 x^{4} - 15 x^{2} - 4

s im pl i f y (x - 2 y)^{3} - (x + 2 y)^{3}

f a c t or n^{2} - 4 n + (- 12)

f a c t or a^{2} \cdot b^{4} + a^{4} \cdot b^{2}
