Question
can someone show me the steps to work out this problem that is diving me nuts..
Directions: Find all positive values for k for which each of the following can be factored.
x^2+x-k
I am completely cluelis towards this problem....i've tried it many different ways....
x= -1/2 +- sqrt(1+4k) /2
Now if you are restricting the x to the real number system, then k can be any postive number.
The factors will be
(x+1/2-1/2 sqrt(1+4k) ) and (x+1/2
+1/2 sqrt(1+4k)) for any value of k>0
can you explain how to get there because i still don't understand
