Algebra: Differentiation

The video tutorial covers differentiation, focusing on finding dy/dx for a given equation. It explains the rules of differentiation, including dropping the power and reducing it by one. The tutorial then moves on to solving for the range of x values where the curve has a negative gradient, using the quadratic formula. The process involves setting up an inequality and substituting values into the quadratic formula to find critical values. The video emphasizes careful substitution and understanding of differentiation rules to solve calculus problems effectively.
