Study Notes
Algebraic Manipulation
Algebraic manipulation is a crucial aspect of mathematical methods, involving the use of various techniques to simplify and solve algebraic expressions.
Index Laws
-
Product of Powers:
a^m × a^n = a^(m+n) -
Power of a Product:
(ab)^m = a^m × b^m -
Quotient of Powers:
a^m ÷ a^n = a^(m-n) -
Power of a Power:
(a^m)^n = a^(mn)
Surds
- A surd is an expression that includes a square root symbol (√)
- Rationalizing the Denominator: multiplying the numerator and denominator by the conjugate of the surd to eliminate the surd from the denominator
Quadratic Equations
-
Quadratic Formula:
x = (-b ± √(b^2 - 4ac)) / 2a -
Factorization: expressing a quadratic equation in the form
a(x - r)(x - s) = 0
Partial Fractions
- Partial Fraction Decomposition: breaking down a rational expression into simpler fractions
- Linear and Quadratic Factors: dealing with linear and quadratic factors in the denominator
Algebraic Identities
-
Difference of Two Squares:
a^2 - b^2 = (a + b)(a - b) -
Sum and Difference of Cubes:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)anda^3 - b^3 = (a - b)(a^2 + ab + b^2)
These algebraic manipulation techniques are essential in solving a wide range of mathematical problems, from simple equations to complex calculus and beyond.
