Answer:

50-25 2/3 - 9 3/4 - 8 1/2 = 6 1/12

Step-by-step explanation:

To do this without a calculator you need to get common denominator

a good choice would be 12 for the common denominator

50 x 12 = 600

25 x 12 = 300

convert to 2/3 to x/12, multiply top and bottom by 4

2/3 x 4 = 8/12

add this to the 300 to get 308/12

same with the other terms

9 x 12 = 108

convert 3/4 to x/12, multiply top and bottom by 3

3/4 x 3 = 9/12

add this to the 108 to get 117/12

and do the same for the 8 1/2

8x 12 = 96

convert 1/2 to x/12, multiply top and bottom by 6

1/2 = 6/12, add this to the 96

do the subtraction and simplify

Use what you have learned to solve the following polynomial equation by either completing the square or using the quadratic form
USPshnik [31]
<span>(x^2-4x-6) factors into:</span>
(x -5.1623)     (x+1.1623)
Therefore x = 5.1623 and      x = -1.1623

(4x^2-8x-2) <span>factors into:
(x -2.2247)  *  (x +2.2474)
</span>
Therefore x = 2.2247   and x=  -0.22474
