x^{23}x-4+4x=10+x^2

解答

x^{23} x - 4 + 4 x = 10 + x^{2}

解答

x \approx 1.10423 \dots, x \approx - 1.13250 \dots

求解步骤

x^{23} x - 4 + 4 x = 10 + x^{2}

展开

x^{23} x - 4 + 4 x : x^{24} - 4 + 4 x

x^{24} - 4 + 4 x = 10 + x^{2}

将

x^{2}

para o lado esquerdo

x^{24} - 4 + 4 x - x^{2} = 10

将

10

para o lado esquerdo

x^{24} - x^{2} + 4 x - 14 = 0

使用牛顿-拉弗森方法找到

x^{24} - x^{2} + 4 x - 14 = 0

的一个解:

x \approx 1.10423 \dots
