Which shows the correct substitution of the values a, b, and c from the equation -2=-x+x^2-4 into the quadratic formula? quadratic formula: x= -b+_ square root b^2-4ac / 2a

Given the equation:

(1)

We need to find a, b and c. So, we know that a quadratic equation is given by:

(2)

Then, we need to order the equation (1) and to adjust it to the equation (2), so:



So, if we compare these two equations, the conclusion is:





(3)

Substituiting a, b and c into (3):



Finally, the results are two values:
