x=33x^2+4x^3-10x^2

解答

x = 33 x^{2} + 4 x^{3} - 10 x^{2}

解答

x = 0, x = \frac{- 23 + 545}{8}, x = \frac{- 23 - 545}{8}

+1

十进制

x = 0, x = 0.04315 \dots, x = - 5.79315 \dots

求解步骤

x = 33 x^{2} + 4 x^{3} - 10 x^{2}

交换两边

33 x^{2} + 4 x^{3} - 10 x^{2} = x

将

x

para o lado esquerdo

4 x^{3} + 23 x^{2} - x = 0

因式分解

4 x^{3} + 23 x^{2} - x : x (4 x^{2} + 23 x - 1)

x (4 x^{2} + 23 x - 1) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or 4 x^{2} + 23 x - 1 = 0

解

4 x^{2} + 23 x - 1 = 0 : x = \frac{- 23 + 545}{8}, x = \frac{- 23 - 545}{8}

解为

x = 0, x = \frac{- 23 + 545}{8}, x = \frac{- 23 - 545}{8}

流行的例子

6 = 20 + 12 t^{2} - t^{3}

x^{6} - 5 x^{3} - 16 = 0

(x - 5) \cdot x^{2} = 14

2 x^{3} = 0

m^{4} + 5 m^{2} + 4 = 0
