Answer:
±
Step-by-step explanation:
First off let's state the quadratic formula
Quadratic formula
For this question our quadratic equation is
Now before we can apply the quadratic formula we first have to set the equation equal to zero. We do this my moving everything to one side and setting it equal to zero.
In this case, we simply move the 2x to the other side making it negative and setting the equation equal to zero.
From here we plug in the values to the quadratic equation.
Now incase you don't know
Coefficient of value
Coefficient of value
The Constant
Now plug in values
To get the values of x using the quadratic formula we have the plug in the values, we also have to both subtract and add the to
Plug in values into formula
Now repeat the steps except subtract from -b rather than add to it.
Final Answer
±
BTW
± = plus and minus
Answer:
c
Step-by-step explanation:
if b and 1 are multiplied by c, c x 1 = c
Answer:
