Summary & Highlights for Three Substitutions In Sequence Ab Cancels And Everything Collapses Math Olympiad
- (x-5)²+(x-4)³+(x-
- (x-1/2)³-(x-1/2)²+x=105/2 → Find x Let y=x-1/2. Then x=y+1/2.
- 7^x+7^(2x)+7^(3x)=14 → Find x Let y=7^x. Then 7^(2x)=y² and 7^(3x)=y³. Equation: y+y²+y³=14. Rearrange: y³+y²+y-14=0.
- x³+x² = 1/8 → Find all real x The 1/8 is the tell. Let y=2x. Substituting x=y/2: y³/8 + y²/4 = 1/8. Multiply by 8: y³+2y²-1=0. The fraction ...
- (x+1)³+x/100=0 → Find all values of x Let y=1/(x+1). Then x=1/y-1.
