Answer:
Step-by-step explanation:
Write "b squared − 2 a c" as b^2 - 4ac.
Now, given that a = 2 , b = − 1 and c = 3
we have (-1)^2 - 4(2)(3), or -23.
If you really meant "b squared − 2 a c" then the end result would be different:
(-1)^2 - 2(2)(3), or -11
Note that "b^2 - 4ac" is the formula for the discriminant of a quadratic equation, whereas "b squared − 2 a c" is not.
