    • 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
