1 Addmath Question a Day
F4C10 Index Number

x - 5√x - 14 = 0
5√x = x - 14
25x = x² - 28x + 196
x² - 53x + 196 = 0
(x - 49)(x - 4) = 0
x = 49 or x = 4

When x = 49,
49 - 5√(49) - 14 = 0

When x = 4,
4 - 5√(4) - 14 = -20 ≠ 0

So x = 4 is rejected, and x = 49 is the only answer.

Do try this kbat c1+c2, for those who didn't try that day, can try today

i really advice all f5 to try this out...its really a nice question...

Maths is always about trying different types of question, when you do a lot of questions,you will familiarize with the questions and just ikut the same approach... so do a lot of (UNUSUAL) questions also, so that u are prepared for most of the type of questions...

I am assuming that ur f5 mid term for addmaths will be in 8 weeks... so why not we all focus 2 bab every 1 week? sunday to Wednesday 1 bab, thurday to Saturday another bab...

tmr we will start from f4c1...

try to do 2 questions each day...
