Polynomials

Second Order
Third Order

Straight Line

A first degree polynomial is always a straight line
y = mx + c
m is the gradient
c is the intercept

Simultaneous Equations

Methods you can use the solve simultaneous equations:
1) elimination
the coefficients of either x or y must be equal in both equations
often - multiply one of the equations and then subtract them

Common Factor

This is the process of finding the numbers (expressions) that multiple together to make a give number (or expression)

InEquation

An equation can be represented as a straight line
An inequation is represented by a region

y = 2x <= 9
2y + x >= 3
