(2 x + 4)^{2} - (x + 3)^{3} = 0

x \approx - 2.29559 \dots

Solution steps

(2 x + 4)^{2} - (x + 3)^{3} = 0

Expand

(2 x + 4)^{2} - (x + 3)^{3} : - x^{3} - 5 x^{2} - 11 x - 11

- x^{3} - 5 x^{2} - 11 x - 11 = 0

Find one solution for

- x^{3} - 5 x^{2} - 11 x - 11 = 0

using Newton-Raphson:

x \approx - 2.29559 \dots

Apply long division:

\frac{- x ^{3} - 5 x ^{2} - 11 x - 11}{x + 2.29559 \dots} = - x^{2} - 2.70440 \dots x - 4.79178 \dots

- x^{2} - 2.70440 \dots x - 4.79178 \dots \approx 0

Find one solution for

- x^{2} - 2.70440 \dots x - 4.79178 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 2.29559 \dots

y, 4 x y^{4} - x^{3} = y^{2} + 5

x^{4} + 4 x^{3} + 2 x^{2} - x + 6 = 0

- 12 x^{3} + 24 x^{2} - 12 x = 0

x^{12} = 5000

4 x^{4} + 15 x^{2} - 4 = 0
