Analyzing the 2014 Examination Questions and Solutions
Example 1: Algebraic Expression Simplification
- Question: Simplify the expression (3x^2 - 2x + 5) - (x^2 + 4x - 3).
- Solution:
- Distribute the subtraction across the second polynomial:
- (3x^2 - 2x + 5) - x^2 - 4x + 3
- Combine like terms:
- (3x^2 - x^2) + (-2x - 4x) + (5 + 3)
- Result: 2x^2 - 6x + 8
This example illustrates the importance of careful distribution and combining like terms, crucial skills assessed in the exam.
Example 2: Differentiation and Application
- Question: Find the equation of the tangent to the curve y = x^3 - 3x + 2 at x = 2.
- Solution:
- Differentiate y with respect to x:
- dy/dx = 3x^2 - 3
- Evaluate at x = 2: dy/dx = 3(4) - 3 = 12 - 3 = 9
- Find y at x = 2: y = (2)^3 - 3(2) + 2 = 8 - 6 + 2 = 4
- Equation of tangent: y - y₁ = m(x - x₁):
- y - 4 = 9(x - 2)
- Simplify: y = 9x - 18 + 4 = 9x - 14
This demonstrates the practical application of differentiation in finding tangent lines, a common exam question type that tests conceptual understanding and calculation skills.
