因式分解 2pirh+pir^2

解答

因式分解

2 π r h + π r^{2}

π r (2 h + r)

求解步骤

2 π r h + π r^{2}

使用指数法则:

a^{b + c} = a^{b} a^{c}

r^{2} = rr

= 2 π r h + π rr

因式分解出通项

r

= r (2 πh + π r)

分解

2 πh + π r : π (2 h + r)

= π r (r + 2 h)

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

f a c t or \frac{2 24}{2}

f a c t or 56 x w + 49 x k^{2} - 24 y w - 21 y k^{2}

f a c t or 9 (a - 2)^{2} + 24 (a - 2) + 16

\frac{d}{d t} ((w) (sin (wt)))
