  this one is easy one... but i forget ler...
  15x² - 77x = 0
  then dunno ler...

  confirm question is this hor?
  u mus find value of x rite?
  
  then either question wrong or answer wrong loh

  Seems like an easy eqn but the answers kind off cheem for e leh.

  I retake my 'o's cause my maths didn't finish the paper... and end up get a b3... and my art... send to moe... when i go collect that time... found the thing broken there... and i was hoping a b4... end up a D7... damm suay...
  how like that jia lat man... how to get 1 for maths like this...
  factorize also got problem...

  could it be that... use the formular thing...
  but 15x² - 77x = 0...
  got a, got b... no c... then use 0 as c???

  yah mah....looks like it's jus simple factorisation and solving equation........but dunno why the ans is like tt......
  probably error in question or answer lah
  
  go to other questions, dun get demoralised bcos of one tt u can't solve......

  hmm... alright...

  Pretty sure the fault lies in the answer. Coz e maths is not cheem and rarely based on calculators to do the job. so ur answers should be left as x = 0 and x = 77/15, no need to simplify further.

  no no no cannot be, thats like turning a simple factorisation into 3 unknowns simultaneous eqns or the use of eigenvalues, which is simply absurb for e maths.

  this is oni used when the equation cannot be factorised or solved by completing sq......
  
  u put in the a,b,c, still give u my jus now the 2 answers wat......

  that one for solving quadratic nia, its the last of last resorts.
