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.
Answer:
(-1.85, -0.15)
Step-by-step explanation:

Here,
x1 = -5.1
x2 = 1.4
y1 = -2
y2 = 1.7
Now substituting the values we have in the equation, we get:-


The coordinates of the midpoint would be = (-1.85, -0.15)

Answer: She combined unlike terms.
Step-by-step explanation:
You can only combine like terms. If a number has a variable, you must make sure that the number you're operating it with has the same variable raised to the same power (if applicable)
6.8w-4.7 is in its simplest form.
To be able to subtract these, 4.7 must have a ''w'' variable as follows;
6.8w-4.7w=2.1w
