\frac{1}{x + 2} = x^{3} + 7 x + 7

x \approx - 0.80567 \dots, x \approx - 2.06174 \dots

Solution steps

\frac{1}{x + 2} = x^{3} + 7 x + 7

Multiply both sides by

x + 2

1 = x^{3} (x + 2) + 7 x (x + 2) + 7 (x + 2)

Solve

1 = x^{3} (x + 2) + 7 x (x + 2) + 7 (x + 2) : x \approx - 0.80567 \dots, x \approx - 2.06174 \dots

x \approx - 0.80567 \dots, x \approx - 2.06174 \dots
