Discriminant review
Discriminant reviewThe discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
Width = Length - 2
Area = L x W
y = x * ( x - 2 )
If the point is ( 2, 0 ): x = 2, y = 0
y = 2 * ( 2 - 2 ) = 2 * 0 = 0 ( area )
Answer:
B ) The area is 0 if the length is 2.
