Factoring with Quadratic Formula and Discriminant

• Square root

• Quadratic formula

• X-intercepts

• Discriminant 

If there are no real solutions, the discriminant is

• zero

• a postive number

• a negative number

• a perfect square

If there is one solution, the discriminant is . . .

• zero

• a postive number

• a negative number

• a perfect square

• 25

• 0

• -25

• -13

The discriminant is

• aX²  + bX  +  c

• b - 4ac
