Solve:
 $4x^2=-4x-1$  

•  $x=-\frac{1}{2}$  

•  $x=-2$  

•  $x=0$  

Does the following quadratic equation have a maximum or minimum value? How can you tell?
 $y=x²+2x-3$  

• Minimum value, because the a value is positive

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative

Solve the following quadratic equation :
 $x^2+7x+12=0$  

•  $x=-2,\ x=-6$

•  $x=-1,\ x=-12$  

•  $x=2,\ x=6$  

The graph of a quadratic function is called

• a line
