Full solution

Q. Fibonnaci leads to\newline−3−x3=1 \sqrt[3]{-3-x}=1
  1. Rewrite equation: Rewrite the equation to isolate the cube root on one side.\newline−3−x3=1\sqrt[3]{-3-x} = 1
  2. Cube both sides: Cube both sides to eliminate the cube root. (−3−x)3=13 (-3-x)^3 = 1^3
  3. Calculate 11 cubed: Calculate 11 cubed.\newline13=11^3 = 1
  4. Expand left side: Expand the left side using the binomial theorem or by multiplying (−3−x)(-3-x) by itself three times.\newline(\(-3-x)^33 = −3-3^33 - 33^22\cdot x - 33\cdot x^22 - x^33
