• quadratic formula

  ax2+bx+c=0
• represents real numbers in quad eq


  a, b, and c

  a=/0
• what do u call sol to quadratics?

  roots or zeros
• in standard form a must be positive
• quad term, linear term, and constant term in quad form are?

  qt = a

  lt = b

  ct = c
• x2=c has 2 possible solutions
• solutions for x2=c

  x=sqrrootc or x=-sqrrootc
• solving quad eq using sqr root method c is a nonnegative real number
• what does SRP mean

  square root property
• quad eq by factoring formula

  ax2+bx=0
• principle of zero products ab=0

  a=0 and b=0
• method under principle of zero prod

  TAE method (trial and error)
• factoring quad eq using AC method

  1. multiply a and c
  2. find factors of ac that sum is b
  3. use factors for bx as sum of 2 terms
• solveing quad eq by completing the sqr

  applicable only to ax2+bx=0
• the discriminant

  pos=2 real solu

  neg=2 complex but not real solu

  zero=1 real solu
• formula for discriminant

  b2-4ac
