63=(3\times (x^3-1))/(x-1)

63 = \frac{3 \cdot ( x ^{3} - 1 )}{x - 1}

x = 4, x = - 5

Solution steps

63 = \frac{3 ( x ^{3} - 1 )}{x - 1}

Simplify

\frac{3 ( x ^{3} - 1 )}{x - 1} : 3 (x^{2} + x + 1)

63 = 3 (x^{2} + x + 1)

Solve

63 = 3 (x^{2} + x + 1) : x = 4, x = - 5

x = 4, x = - 5

Verify Solutions

Find undefined (singularity) points:

x = 1

Combine undefined points with solutions:

x = 4, x = - 5

8 + \frac{6}{x} = x + 9

8 = \frac{16}{x}

\frac{3 x - 1}{x} = \frac{5}{2}

\frac{x}{x + 4} = \frac{32}{x ^{2} - 16} + 6

0.02 = \frac{1}{x}
