Answer:
The quadratic equation has one real root with a multiplicity of 2.
Step-by-step explanation:
Given a quadratic equation:
You can find the Discriminant with this formula:
<em> </em>In this case you have the following quadratic equation:
Where:
Therefore, when you substitute these values into the formula, you get that the discriminant is this:
Since , the quadratic equation has one real root with a multiplicity of 2 .
Answer:
y = 1
Step-by-step explanation:
The line is horizontal and goes through the y axis.
Hence the equation is y = 1 because the line stays on this point forever.
144 because when you divide them and simplify
<u>No solution</u>: because the absolute value is positive and can't equal a negative
|x| = -1
<u>One solution: </u>because zero only has one sign
|x| = 0 ⇒ x = 0
<u>Two solutions:</u> absolute value is positive whether x is positive or negative.
|x| = 2 ⇒ x = 2 or x = -2
