When factorising cubics using the factor theorem, Use the known factor then factorise the remaining quadratic
always remember to...
Where does the graph of (-p,q)
y=(x+p)² + q
have a stationary point?
nCr = n!/r!(n-r)!
When solving a quadratic inequality, always Sketch the graph
remember to...
First step when adding or subtracting fractions Find a common denominator (by cross multiplication)
First step when solving an equation involving Multiply through by a number which clears both fractions
fractions
Quadratic Formula x = {-b +/- √(b²-4ac)}/2a
Discriminant b²-4ac
Positive Discriminant b²-4ac > 0 2 real roots
Discriminant b²-4ac = 0 1 repeated root
Negative Discriminant b²-4ac < 0 No real roots (no solution)
Number of roots = The number of times the function meets the x axis
Circle Equation (x-a)² + (y-b)² = r²
Centre of the circle (x-a)² + (y-b)² = r² (a, b)
Circle Theorem 1 An angle subtended from the diameter is 90 degrees
Circle Theorem 2 A chord and its bisector are perpendicular
Circle Theorem 3 A tangent and the radius are perpendicular
How to find the minimum Complete the square then find the smallest y value
y=-f(x) Reflect in x axis
y=f(-x) Reflect in y axis
y=f(x-a) Translate 'a' units right
