x^{2} + 2 x - 9 = 2 x^{2} x

x \approx - 1.68296 \dots

Solution steps

x^{2} + 2 x - 9 = 2 x^{2} x

Expand

2 x^{2} x : 2 x^{3}

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

Switch sides

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

Move

9

to the left side

2 x^{3} + 9 = x^{2} + 2 x

Move

2 x

to the left side

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

Move

x^{2}

to the left side

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

Write in the standard form

a_{n} x^{n} + \dots + a_{1} x + a_{0} = 0

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

Find one solution for

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

using Newton-Raphson:

x \approx - 1.68296 \dots

Apply long division:

\frac{2 x ^{3} - x ^{2} - 2 x + 9}{x + 1.68296 \dots} = 2 x^{2} - 4.36592 \dots x + 5.34770 \dots

2 x^{2} - 4.36592 \dots x + 5.34770 \dots \approx 0

Find one solution for

2 x^{2} - 4.36592 \dots x + 5.34770 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 1.68296 \dots

j (x) = x^{4}

x, 6 x^{2} (m + 2) x + 3 = 0

x^{3} + x^{2} - 22 x - 40 = 0

30 π r^{2} + 4 π r^{3} = 4500

2 m^{3} - 250 = 0
