Year 9 Linear Equations Test — Summary Sheet
1. Simplifying Algebraic Expressions
How to do it:
Multiply numbers and letters together.
Combine like terms (same letters and powers).
Example:
−2ac×4bd=−8abcd-2ac \times 4bd = -8abcd
Example:
5ab−8b2a+ba=5ab−8ab2+ab=−8ab2+6ab5ab - 8b^2a + ba = 5ab - 8ab^2 + ab = -8ab^2 + 6ab
2. Expanding Brackets (Distributive Law)
How to do it:
Multiply everything inside the bracket by what is outside.
Example:
−4(x+7)=−4x−28-4(x + 7) =...
VLSI (Very Large Scale Integration) integrates thousands to millions of transistors on a single chip, drastically reducing size, cost, and power consumption.
Moore’s Law states the number of transistors in a dense IC doubles approximately every 18 months. Second Law: Cost of semiconductor fabrication plant doubles every 4 years.
ASIC (Application Specific Integrated Circuit) is a custom IC designed for specific applications. Types include Full-Custom, Semi-
