Which shows the correct substitution of the values a, b, and c from the equation - 2 = - x + x2 - 4 into the quadratic formula? Quadratic formula: x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction

a = 1

b = - 1

c = - 2

Step-by-step explanation:

We reorder the equation in such way that let us see the usual

ax² + bx + c = 0

Then the original quation is:

-2 = - x + x² - 4 ⇒ 0 = 2 - x + x² - 4 ⇒ x² - x - 2 = 0

Now we are able by simply inspection to identify a, b. c comparing our equation with the general equation so:

a = 1

b = - 1

c = - 2

i mean my guy the answer should be D then
