因式分解 4y^{12}-41y^7-33y^2

解答

因式分解

4 y^{12} - 41 y^{7} - 33 y^{2}

y^{2} (4 y^{10} - 41 y^{5} - 33)

求解步骤

4 y^{12} - 41 y^{7} - 33 y^{2}

使用指数法则:

a^{b + c} = a^{b} a^{c}

y^{7} = y^{5} y^{2}

= 4 y^{10} y^{2} - 41 y^{5} y^{2} - 33 y^{2}

因式分解出通项

y^{2}

= y^{2} (4 y^{10} - 41 y^{5} - 33)

- 16 (6)^{2} + x (6) + 3 = 0

s im pl i f y ln ∣ 1 ∣

\frac{x + 1}{x - 1} + 2 \geq 0

(x - 4)^{2} + 3 (x - 4) - 18 = 0

0 = 7 x + 4.9 x^{2} - 8
