Answer: 17/60 = 0.283333333333
25/60 = 0.416666666667
54/72 = 0.75
31/44 = 0.704545454545
Step-by-step explanation:
2x^2-8x-24=0
Divide the whole equation by 2.
x^2-4x-12=0
Complete the square
x^2-4x+4-16=0
(x-2)^2 -16=0
(x-2)^2=16
Take the square root of each side.
(x-2)=4 and (-(x-2))=4
x=6 and x=-2
Our Equation is

which means

Now we have to find this ration

Inserting value of a into this equation




1/4 / 1/2 =
1/4 x 2/1 = 2/4 = 1/2
(2,0) (5.0) (5,3) (2,3)
(2,0) (-1,0) (2,3) (-1,3)
