To factor ax^2+bx+c, you look for two factors of a and two factors of c, one factor of a multiple one factor of c, the other factor of a multiple the other factor of c, the sum of the two products makes b
in this case, the two factors of a is 1 and 2, the two factors of c, -36, are -12 and 3. Write them in the following format:
1     -12

2      3
do a "cross-times", that is, 1 times 3, 2 times -12
(1 multiple 3) +(2 multiple -12)=-21
if you don't get a -21, try other factors of -36, switch the factors up/down till you find the right fit.
so (x-12)(2x+3) is the anwer

Burnwood Tech plans to issue some $50 par preferred stock with a 8% dividend. A similar stock is selling on the market for $65.
Vanyuwa [196]

Answer:

6.5%

Step-by-step explanation:

The formular used to calculate the cost of preferred stock is:

= Fixed dividend/Net proceeds

Fixed dividend= $50 × 8/100

= $50×0.08

=$4

Net proceeds= Market price-Flotation costs

= $65-(6/100×$65)

= $65-(0.06×$65)

= $65-3.9

= $61.1

Therefore cost of preferred stock is

= 4/61.1 ×100

= 0.065×100

= 6.5%

Hence the cost of preferred stock is 6.5%
