Instructions:
- Answer all questions.
- Show all workings for full marks.
- Each question carries equal marks.
Section A: Algebraic Expressions
- 1. Simplify the expression: 3x + 5x - 2x + 7.
- 2. Expand the expression: (x + 4)(x + 3).
- 3. Factorize the expression: x^2 + 5x + 6.
- 4. If a = 2 and b = 3, evaluate the expression: 2a^2 - 3b + 4.
Section B: Algebraic Identities
- 5. Verify the identity: (a + b)^2 = a^2 + 2ab + b^2 by substituting a = 1 and b = 2.
- 6. Use the identity a^2 - b^2 = (a + b)(a - b) to factorize: 9 - x^2.
- 7. Expand using the identity (x - 5)^2.
- 8. If p = 4 and q = 5, find the value of p^2 + q^2 - 2pq.
Section C: Application of Identities
- 9. If the length of a rectangle is represented by (x + 2) and the width by (x - 2), find the area using the identity for the difference of squares.
- 10. A triangular garden has sides of lengths represented by (x + 1), (x + 4), and (x + 5). Find the expression for the perimeter.
Conclusion:
- Review your answers before submission.
- Ensure clarity and neatness in your work.
This mock test is designed to assess your understanding of algebraic expressions and identities. Good luck!
