展开 (100(x^2+10x+100))/((x+10)^2)

解答

展开

\frac{100 ( x ^{2} + 10 x + 100 )}{( x + 10 ) ^{2}}

\frac{100 x ^{2} + 1000 x + 10000}{x ^{2} + 20 x + 100}

求解步骤

\frac{100 ( x ^{2} + 10 x + 100 )}{( x + 10 ) ^{2}}

(x + 10)^{2} = x^{2} + 20 x + 100

= \frac{100 ( x ^{2} + 10 x + 100 )}{x ^{2} + 20 x + 100}

乘开

100 (x^{2} + 10 x + 100) : 100 x^{2} + 1000 x + 10000

= \frac{100 x ^{2} + 1000 x + 10000}{x ^{2} + 20 x + 100}

e x p an d - (\frac{2 ^{3}}{3}) - (\frac{2 ^{2}}{2}) + 12

e x p an d P (1, - 2) y Q (3, 4)

e x p an d \frac{( 3 - 5 + x ) ( 2 + 8 - x )}{x - 4}

e x p an d 2 (a + 2 e)

e x p an d \frac{x}{( x + 3 ) ( x - 2 )}
