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:
-12
Step-by-step explanation:
z+z+z
-4+-4+-4
-8+-4
-12
An equation does not always have a solution. Sometimes, an equation can have a variable that does not equal the remaining value on the other side. For example, root negative x could never equal a number squared.
√-x ≠ 14²
This equation cannot have a solution because you can't square any number to get a negative solution. Therefore, x= no solution.
A negative number is a number that isn’t going down and a positive is a number that is going up on a number scale
<span>x−<span>2/7</span></span>=<span>5/<span>7
so this means x = 1</span></span>
