The complex solution to a quadratic equation is below. write this solution in standard form, a+bi, where a and b are real numbers. what are the values of a and b.

Answers:    a = 1/4,    b = 2

====================================

Work Shown:

sqrt(-256) = sqrt(-1*256)

sqrt(-256) = sqrt(-1)*sqrt(256)

sqrt(-256) = i*16

sqrt(-256) = 16i

----------

The given equation

turns into

Compare this to and we see that a = 1/4 and b = 2.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
