Sorry folks.....a kinda tough maths question here

rainee SG

x^2=4, how would u do?

not just x=+/- square root (4) Laughing

ndmmxiaomayi SG

You from RI? This question hard leh.

rainee SG

the working si bei long...need to scan if he wans to see the working Laughing

ndmmxiaomayi SG

hanor hanor

rainee SG

i m still waiting for the answer... Laughing

dragg SG

math really sucks.

ndmmxiaomayi SG

I give up. I don’t know how to do question 2. I stuck somewhere.

I got...

t=x(4p-9) / (9+4p)

dunno right or not... Rolling Eyes

rainee SG

lol cool and me posted at same time, but me too lazy to show working ahahaha Mr. Green Twisted Evil

This time, I edited. Confirmed liao.

p = 5p/3 - sqrt((p(x + t)/x - t)
p - 5p/3 = - sqrt((p(x + t)/x - t)
(square both sides): p^2 - 10p^2/3 + 25p^2/9 = p(x + t)/x - t
(X9 on both sides): 9p^2 - 30p^2 + 25p^2 = 9p(x + t)/x - t
4p^2 = 9p(x + t)/x - t
4p^2/9p = x + t/x - t
4p/9 = x + t/x - t
(cross multiply): 4px - 4pt = 9x + 9t
4px - 9x = 9t + 4pt
4px - 9x = t(9 + 4p)
t = 4px - 9x/9 + 4p

(simplify yourself)

CoolMyth SG

Still got t on right hand side. Cool

ndmmxiaomayi SG

I know, so I am editing my reply. Wait a while.

Mr Fugue SG

all the handwriting so cute~!! Laughing

Steps: 1. bring down "a" to the left side
2. sq. root both sides
3. bring "-b" to become "+b" on the left side.

Answer: M = (p/a)^(1/2) + b

Laughing Mr. Green

jay_rocks SG

p=a(m-b)^2
p/a=(m-b)^2
square root p/a + b = M

ans

From above...

p - (5p)/3 = -(square rt)( (p(x + t)) / (x - t) )

-(2p / 3 )= -(square rt)( (p(x + t)) / (x - t) )

2p/3 = (square rt)( (p(x + t)) / (x - t) )

Squaring both sides,

(2p/3)^2 = (p(x + t) ) / (x - t)

4p/9 = (x+t) / (x-t)

x(4p/9) - t (4p/9) = x + t

x (4p/9 - 1) = t (4p/9 + 1)

Therefore,

t = [x (4p/9 - 1)] / (4p/9 +1)

shade343 SG

Wrong.

(a-b)^2 is not = (a^2-b^2)

All of your solutions so boring sia. Make it more interesting like dis.

Q. How to get 'eM (the ladies, your honey) from Pee, Ass and Bee?

Solution.

Pee = Ass ('eM - Bee)Squared

You bringa Ass down, near Pee.
After Pee is all a over your Ass, faira and Square, Root it outta.
Den Add a Bee for honey, to your a Squarely Rooteda Pee over Ass a
And a now a you've gotta 'eM.

'eM=Bee + Squarely Rooted (Pee/Ass)
