This chapter introduces different types of numbers, including:
Key Formulas:
Rational Number: \( \frac{p}{q} \), where \( p \) and \( q \) are integers and \( q \neq 0 \)
Irrational Numbers: Numbers that cannot be expressed as \( \frac{p}{q} \)
This chapter focuses on:
Key Formulas:
\( a^m \times a^n = a^{m+n} \)
\( \frac{a^m}{a^n} = a^{m-n} \)
\( (a^m)^n = a^{mn} \)
\( a^0 = 1 \)
Rationalisation refers to removing the square root (or cube root) from the denominator of an expression. Topics covered:
Key Formulas:
For \( \frac{1}{\sqrt{a}} \), multiply by \( \frac{\sqrt{a}}{\sqrt{a}} \)
For \( \frac{1}{a+\sqrt{b}} \), multiply by \( \frac{a-\sqrt{b}}{a-\sqrt{b}} \)
Algebraic identities are essential tools in simplifying and solving expressions. Key topics:
This chapter teaches breaking down algebraic expressions into their simplest components:
Key Formulas:
\( a^2 - b^2 = (a+b)(a-b) \)
\( x^2 + (a+b)x + ab = (x+a)(x+b) \)
This extends factorisation to polynomials:
Key Formulas:
If \( f(x) \) is a polynomial, and \( f(a) = 0 \), then \( (x-a) \) is a factor of \( f(x) \).
