If u fit add dis 1 i go happy ooooo,...........express 5x-12/(x-2)(x-3) in partial fractions.........,...can't even attempt dis 1

let 5x-12/(x-2)(x-3)= A/x-2 +B/x-3
multiply all sides by the l.c.m
5x-12=A(x-3) +B(x-2)
our target is to eliminate either A or B on the RHS
put x=2 into to eliminte B
5(2)-12= A(2-3)
10-12=-1A
-2=-A
A=2
to eliminate A we put x=3
5(3)-12=B(3-2)
15-12=1B
B=3
substituting...
2/x-2 + 3/x-3

if u lyk Call me oliver twist buh help me suffix dis ,1..............find d coordinate of the minimum point for d eqn y=4t^2-40t+300 ........plz oooo

dy/dt=8t-40
at minimum point dy/dt=0
8t-40=0
t=5
the value of y is gotten by putting t=5 into...
y=4t^2 -40t +300
y=4(5)^2 -40(5) +300
y=100-200+300
y=200
coordinates is (5, 200)

Errm..,sm1 shld help me solve this and state his steps plz,
calculate sin(A+B) If sinA=3/5 And cosB=5/13
I got 99/65 buh it aint in d option.....

sin(A+B)...openin d bracket willbe...
sinAcosB +cosAsinB
note:sinA=3/5 cosB=5/13 cosA=4/5 sinB=12/13
den substitute d values...ans is 63/65

I wrote my jamb dere....dat was last month....i wil say d university is nice but jux 80% completed....i guess he is in haste to approve it cos d incoming govt may not...he is no frend of buhari

beatsbyj2g:
u no knw has I hate English reach ni n am starting with Chen

Wen preparing for an exam like jamb....u leave no subject behind u shud note which subject u are gud at or has flaws...den work wel on d ones wit flaws coz daz d subject... dat wil make ur scores decrease...u shud ENDEAVOUR to create a balance b/w d 4 subjects

that's d only way u can get to d moon u are aiming at #jux my opinion

beatsbyj2g:
I didn't say am aiming 35 am just telling him which score he should Neva fall under


I aim for d moon n I land on it #determination #teamFUTA

Oga u shud neva start wit maths or phy....nd u need'nt end wit eng coz by den ur brain wil b vry hot daz wen u myt fall prey to d eng questns....as u start wit ur brain stil fwesh.....start wit d eng...nd end wit maths#jux my point

beatsbyj2g:
do d one u are good in first.
For example if u choose physics first, we all know dat physics is a mixture of calculations n theoretical question so u do one first cal. First den theoretical ones in other to avoid wasting time coz cal. Takes more time but theory takes reason.

For Mr I'd do chemistry (my best subject) den physics theoretical question (am not dat good in cal. Coz of fake teachers ) den mathematics cal. Den I go back to physics cal. B4 ending with English.

Knowing fully well dat
Math - 50 question-- 2 marks each
Phy - same
Chem - same
English - 100 question -- 1 mark each

Altogether 400 Mark_____ getting 35 in phy Chen n math would = 35* 3 = 105 * 2 = 210
So maybe at least 30 marks in English ( in case of mistake in d above 35 score objective)
210 + 30 =240 marks


Btw no body is expecting u to get 350/400 dey just expect u to get admission .

ans 35 correctly in each can't get u 240...moreover u shud b aiming d 50...u shud b aiming at d moon so wen u fall, it wil b b/w d stars
