Which shows the correct substitution of the values a, b, and c from the equation –2 = –x + x2 – 4 into the quadratic formula? Qu
Likurg_2 [28]

Answer:

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
