x^{4} + x^{3} + x^{2} + x^{1} = 1

x \approx 0.51879 \dots, x \approx - 1.29064 \dots

Solution steps

x^{4} + x^{3} + x^{2} + x^{1} = 1

Refine

x^{4} + x^{3} + x^{2} + x = 1

Move

1

to the left side

x^{4} + x^{3} + x^{2} + x - 1 = 0

Find one solution for

x^{4} + x^{3} + x^{2} + x - 1 = 0

using Newton-Raphson:

x \approx 0.51879 \dots

Apply long division:

\frac{x ^{4} + x ^{3} + x ^{2} + x - 1}{x - 0.51879 \dots} = x^{3} + 1.51879 \dots x^{2} + 1.78793 \dots x + 1.92756 \dots

x^{3} + 1.51879 \dots x^{2} + 1.78793 \dots x + 1.92756 \dots \approx 0

Find one solution for

x^{3} + 1.51879 \dots x^{2} + 1.78793 \dots x + 1.92756 \dots = 0

using Newton-Raphson:

x \approx - 1.29064 \dots

Apply long division:

\frac{x ^{3} + 1.51879 \dots x ^{2} + 1.78793 \dots x + 1.92756 \dots}{x + 1.29064 \dots} = x^{2} + 0.22814 \dots x + 1.49348 \dots

x^{2} + 0.22814 \dots x + 1.49348 \dots \approx 0

Find one solution for

x^{2} + 0.22814 \dots x + 1.49348 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solutions are

x \approx 0.51879 \dots, x \approx - 1.29064 \dots

(17 x - 11)^{3} - (17 x - 11) = 0

m^{3} = 1000

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

- 6^{3} = y^{6}

2 x^{3} - 12 x^{2} + 8 x = 0
