Video Timeline Factoring and Simplification (0:30–1:17): The presenter starts by factoring b from the numerator, rewriting the expression as b(b² − 2) / 2b. The common factor b cancels out, simplifying the equation to (b² − 2) / 2 = 7. Cross-Multiplication and Isolation (1:17–2:15): Next, cross-multiplication is applied, giving b² − 2 = 14. Adding 2 to both sides isolates the squared term, resulting in b² = 16. Finding the Value of b (2:15–3:12): Taking the square root of both sides yields two possible solutions. Since square roots can be positive or negative, the presenter concludes that b = ±4, meaning the values of b are 4 and −4. Proof / Verification (3:12–4:52): To confirm the solution, the video substitutes b = 4 back into the original expression. The result equals 7, matching the right-hand side of the equation and verifying the solution The presenter starts by factoring b from the numerator, rewriting the expression as b(b² − 2) / 2b.
