I'm not getting the correct answer for question 1 ... although I used the exact method as given in the ms....
It's pretty simple reallyy... only if someone cud show the calculations bcz maybeI'm making an error there....
thankss...
X<-5 and x>-5/3 if ur answer was right.Solve the inequality I x I < I 5 + 2x I
I got two values to x as -5 and -5/3 and they are right ,
but how to make the inequalities finally
oohh yeahh u were rigghhtt!! thanks a lot!!View attachment 37509
I had my calculator on gra so my D was wrong. Then i switched to deg and answer was right. That might be the case with you.

I got the right ans with both!
Hello mateI would like to know the answer to this as well.. How many marks is it worth and which year/paper mate?
You can write anything! This is because it is not specified in the question if it is base-e , or base 10X and Y are related by x^n y = c
When we form equation it should be : nlogx +logy = logc
But in marking scheme they use (( ln )) instead of log ! how comes ?
Hello mate
The exact question(7) of this O/N 2005 was:
" 2x^3 + x^2 + 25 = 0 has one real root and two complex roots. verify that 1+2i is one of the complex roots"
yes, I know how to verify. But instead if the question was asked "what are the complex and real roots of this equation?" Then, what should I do?
