Introduction to Linear Inequality

       The symbols used to denote quadratic inequalities are ________.

•  $<,>,\le,\ge$   

•  $<,>,\ne,=$  

•   $\le,\ge,\equiv,\cong$  

•  $<,\le,\sim,\approx$  

The following are standard forms of quadratic inequalities except ________.
 

• a $x^2$   + bx  +  c  $>$   0

• a $x^2$   + bx  + c  $<$   0

•  a $x^2$  + bx +  c  $\ge$   0

•  

  a $x^2$   + bx  +  c $\le$ 0

• a $x^2$  +  bx  +  c  $=$  0
