For this case we have that by definition, the discriminant of a quadratic equation 
, is given by:
: Two different real roots
: Two equal real roots
: Two different complex roots
If we have 
, then:
Substituting the values:
Thus, we have two equal real roots.
ANswer:
We have two equal real roots.
2 is a factor of 20 and not a multiple of 5
Sorry I don’t really know the answer
Answer:
top left
Step-by-step explanation:
take a vertical line and place it on the graph. Then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once. ( it only crossed once)
Answer:
x = -5
Step-by-step explanation:
The equation y = x^2+10x+25 can be factored to (x+5)^2
when (x+5)^2 = 0
x = -5
meaning the equation has a line of symmetry at x = -5
