해법

단순화

\frac{x ^{3}}{( 6.4 + x ) ^{2}} - 55.04

\frac{- 2254.4384 - 704.512 x - 55.04 x ^{2} + x ^{3}}{( 6.4 + x ) ^{2}}

솔루션 단계

\frac{x ^{3}}{( 6.4 + x ) ^{2}} - 55.04

분수 규칙 적용:

a + \frac{b}{c} = \frac{a c + b}{c}

= \frac{- 55.04 ( 6.4 + x ) ^{2} + x ^{3}}{( 6.4 + x ) ^{2}}

- 55.04 (6.4 + x)^{2} + x^{3}

간소화하다 :

- 2254.4384 - 704.512 x - 55.04 x^{2} + x^{3}

= \frac{- 2254.4384 - 704.512 x - 55.04 x ^{2} + x ^{3}}{( 6.4 + x ) ^{2}}
