(am)n = a
a0 = 1
A quadratic expression has the form ax2 + bx + c , where a, b and c are constants and a 0
Surds
ab = a × b
a a
b = b
When rationalizing surds:
The form 1a is multiplied from the top and the bottom by a
The form 1
a+ b
is multiplied from the top and the bottom by a - b
The form 1
a-b
is multiplied from the top and the bottom by a + b
Quadratic Functions
The formula
x = -b±2

x2 + bx = (x + b
2 ) - ( 2 )
To sketch a quadratic graph:
