Answer:

(1+√7,0),(1−√7,0)

Step-by-step explanation:

You can't factor the expression evenly, so use the quadratic formula.

a = 2

b= -4

c= -12

$\frac{-b+\sqrt{b^{2}-4ac } }{2a}$

$\frac{4+\sqrt{16{}-4(2)(-12)} }{2(2)}$

$\frac{4+\sqrt{16-4(-24)} }{4}$

$\frac{4+\sqrt{16+96} }{4}$

$\frac{4+\sqrt{112} }{4}$

$\sqrt{112} = 4\sqrt{7}$

End result: (1+√7,0),(1−√7,0)

The graph shows the number of Wilmbeldon championships of several countries. Write the ratio the championships won by the Austra

Hoochie [10]

If I am reading this correctly...the ratio would be
Austalia championships: the total of countries championships

for example australia = 18 and the other countries have 300
ratio would be 18:300 or 18/300

Then simplify 3:50 or 3/50

Hope this was helpful!
