So I wrote a test last Friday and the question was to complete the square which I know how to do but they gave me this crazy equation
5x2 = -x
5x2 + x = 0
(x2 + x + x/5/2) - x/5/2 = 0
(x2 + x/5 + x/5/2) = x/5/2
this is where I got stuck
I see what I should be doing but I fail to get the grip of the equation.
seeing that you factorized the 5x^2 then 5(x^2 + 1/5x + 1/100) -1/20
which I am not getting in this case since I usually workout the three term factoring using the quadratic formula which didn't workout
because of the x confusing me.
hope you understand what I mean by this
