因式分解 32x^2y-8y

解答

因式分解

32 x^{2} y - 8 y

8 y (2 x + 1) (2 x - 1)

求解步骤

32 x^{2} y - 8 y

因式分解出通项

8 y : 8 y (4 x^{2} - 1)

= 8 y (4 x^{2} - 1)

因式分解

4 x^{2} - 1 : (2 x + 1) (2 x - 1)

= 8 y (2 x + 1) (2 x - 1)

j o in 1 + \frac{π}{4}

(0.229) (55) + 0 = (0.229) (40) + (0.046) v^{2}

f a c t or x^{3} - 37 x + 84

s im pl i f y (343 x^{9})^{\frac{2}{3}}

- y = 2 - y^{2}
