a^{3} - 3 a^{2} = 240

a \approx 7.39211 \dots

Solution steps

a^{3} - 3 a^{2} = 240

Move

240

to the left side

a^{3} - 3 a^{2} - 240 = 0

Find one solution for

a^{3} - 3 a^{2} - 240 = 0

using Newton-Raphson:

a \approx 7.39211 \dots

Apply long division:

\frac{a ^{3} - 3 a ^{2} - 240}{a - 7.39211 \dots} = a^{2} + 4.39211 \dots a + 32.46702 \dots

a^{2} + 4.39211 \dots a + 32.46702 \dots \approx 0

Find one solution for

a^{2} + 4.39211 \dots a + 32.46702 \dots = 0

using Newton-Raphson:

No Solution for

a \in R

The solution is

a \approx 7.39211 \dots

s^{5} - s^{3} - s^{2} + 1 = 0

a^{5} = 7

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

x^{4} - 18 x^{2} + 32 = 0

x^{3} - 5 x^{2} + 6 x - 1 = 0
