(3x-8)^4(x-1)^3(x+1)<= 0

解答

(3 x - 8)^{4} (x - 1)^{3} (x + 1) \leq 0

- 1 \leq x \leq 1 or x = \frac{8}{3}

间隔符号

[- 1, 1] \cup x = \frac{8}{3}

十进制

- 1 \leq x \leq 1 or x = 2.66666 \dots

求解步骤

(3 x - 8)^{4} (x - 1)^{3} (x + 1) \leq 0

确定区间

- 1 \leq x \leq 1 or x = \frac{8}{3}

3 X - 6 + 4 X = 7 - 3 X + 5

(x + 4) (5 x + 9) - x^{2} + 16 = 0

- 52 a^{2} + 5119 a - 54421 = 40000
