The thing that i learnt this week are: Solving Quadratic Inequalities in One Variable, Graphing Linear Inequalities in Two Variables, Graphing Quadratic Inequalities in Two Variables.
Quadratic Inequalities is One Variable is in quadratic equation have equals sigh replaced with an inequality sigh, this is quadratic inequality in one variable.
A quadratic inequality in one variable can be written in general form as:
ax^+bx+c<0 ax^+bx+c<=0
ax^+bx+c>0 ax^+bx+c>=0
where a,b and c are constants and a not=0
