16 x^{3} + 23 x^{2} + 198 x - 209 = 0

x \approx 0.90181 \dots

Solution steps

16 x^{3} + 23 x^{2} + 198 x - 209 = 0

Find one solution for

16 x^{3} + 23 x^{2} + 198 x - 209 = 0

using Newton-Raphson:

x \approx 0.90181 \dots

Apply long division:

\frac{16 x ^{3} + 23 x ^{2} + 198 x - 209}{x - 0.90181 \dots} = 16 x^{2} + 37.42908 \dots x + 231.75420 \dots

16 x^{2} + 37.42908 \dots x + 231.75420 \dots \approx 0

Find one solution for

16 x^{2} + 37.42908 \dots x + 231.75420 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 0.90181 \dots

x^{3} = \frac{- 125}{216}

x^{3} + 2 x^{2} + 10 x = 20

3 x^{4} + 2 x^{3} - 9 x^{2} + 4 = 0

d^{4} - 1 = 0

x^{2} + 4 x^{3} + 5 x^{2} + 2 x^{2} = 0
