化简 ((x^3+x^2+x+6))/((x+2))

解答

化简

\frac{( x ^{3} + x ^{2} + x + 6 )}{( x + 2 )}

x^{2} - x + 3

求解步骤

\frac{x ^{3} + x ^{2} + x + 6}{x + 2}

因式分解

x^{3} + x^{2} + x + 6 : (x + 2) (x^{2} - x + 3)

= \frac{( x + 2 ) ( x ^{2} - x + 3 )}{x + 2}

约分:

x + 2

= x^{2} - x + 3

s im pl i f y ((a \frac{3}{100} a [7]) - a [10]) \cdot a [5]

f a c t or 4 x^{3} + 2 x - 6

f a c t or 2 x^{2} + 2 y^{2} - 4 x y

s im pl i f y \frac{3 x ^{3} + 4 x ^{2} - 3 x + 2}{x + 2}

f a c t or 9 a^{4} - a^{2} + 16
