Ineed !

i need to determine the roots of each quadratic equation by compleating the square, then it says to round to the nearest

x²-2x-4=0

how! ? 12 !

also pls provide step by step so i can do this on my own!

Step-by-step explanation:

First, you have to factor.

Then you set your factors to 0.

Your answers will be x=3.24 and x=-1.24

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
