解答

展开

(2 x + 5 y) (2 x - 5 y)

4 x^{2} - 25 y^{2}

求解步骤

(2 x + 5 y) (2 x - 5 y)

Apply Difference of Two Squares

(2 x + 5 y) (2 x - 5 y) : 4 x^{2} - 25 y^{2}

= 4 x^{2} - 25 y^{2}

s im pl i f y (6 x^{5} y^{4})^{3}

s im pl i f y 54 x^{3}

s im pl i f y \frac{x ^{2} + 10 x + 24}{\frac{x + 6}{x + 4}}

f a c t or 8 x^{2} + 12 x

\frac{2 5 ^{- 1}}{5 ^{- 2}} \div \frac{0. 5 ^{- 2}}{0. 1 ^{- 3}}
