Help a girl out pls What are the exact solutions of x2 - X-4 = 0, where -b + √b² - 4ac X= 2a Ox= -115 2 Ox= 11 15 2 O x = 1:17 2 0x==137​

    1 ± sqrt(17)

 x =

            2

Step-by-step explanation:

x^2 - x - 4 =0

Using the quadratic equation

     -b ± sqrt(b^2 -4ac)

 x =

            2a

Where ax^2 +bx +c  

We know a =1  b = -1  c = -4

     -(-1) ± sqrt((-1)^2 -4(1)(-4))

 x =

            2(1)

     1 ± sqrt(1 +16)

 x =

            2

     1 ± sqrt(17)

 x =

            2

es todo o no o que hacen hola

the diver is 33 feet below the surface.
