解答

展开

(4 x + 6 y) (4 x - 6 y)

16 x^{2} - 36 y^{2}

求解步骤

(4 x + 6 y) (4 x - 6 y)

Apply Difference of Two Squares

(4 x + 6 y) (4 x - 6 y) : 16 x^{2} - 36 y^{2}

= 16 x^{2} - 36 y^{2}

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

f a c t or 9 a^{2} b^{3} - 16 a^{4} b

s im pl i f y \frac{x ^{7}}{( a ^{2} - x ^{2} )}

f a c t or y^{3} + y^{2} - y - 1

s im pl i f y x^{- 1} \cdot 2 x^{\frac{1}{2}}
