finally the value of k will be 4...2^2+2k-12=0
therefore k = 4...
therefore k = 4...
msbhanusepb1bl6:
yes
how could I do that
i am percent right
means what
as it is given that x = 2 is a root of that equation first one.... means X - 2 = 0.... therefore X equals to 2.... substituting the value of x we get the answer as 4
plz.reply fast
I mean to say that if X = 2 is a root of the given equation first one then it should satisfy the equation means the final answer should be zero... why we have to put x equals question
x=2 in the equation
hmm. u r right
if u need any help then send me your question
