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

V125BC [204]

Total students = 28

Students with brown eyes = 19

students wear glasses = 13

Not brown eyes or no glasses = 7


Not brown eyes = 28 - 19 = 9

Not wearing glasses = 28 - 13 = 15

Not brown eyes and wearing glasses = 15 - 9 = 6

Brown eyes and wearing glasses = 13 - 6 = 7 <==== answer
