Homework  1.10  Solving  Quadratics  Part  2                 Solutions    Answer  the  following  questions  about  solving  quadratics.    

1.  What  are  the  solving  methods  to  solve  for  quadratic  equations?  Fill  in  the  methods  in  the  diagram  below.                  2.  In  order  to  solve  for  x  by  using  the  taking  square  root  method,  you  must  isolate  the  quadratic  term.    Find  the  solutions  of  the  quadratics.    

3.  !! + 4 = 0         2.   ! + 3 ! + 6 = 18       3.   2! + 6 ! − 8 = 24  

 4.  !! + 21 = 5         5.  3 ! + 4 ! = −9       6.  2!! + 338 = 0  

 7.  4 ! + 5 ! = −64       8.  2!! + 338 = 0         9.  −9!! = 243  

 10.  The  tallest  building  in  the  USA  is  in  Chicago,  Illinois.  It  is  1450  ft.  tall.  The  equation  of  rise  and  fall  is  represented  by  ! = −16!! + 1450.  How  long  would  it  take  a  penny  to  drop  from  the  top  of  the  building  to  the  ground?     ! ≈ 9.52  !"#$%&!    

! = 2!, ! = −2!   ! = −3+ 2 3,        ! = −3− 2 3    

! = −3+ 2 2,  ! = −3− 2 2  

! = 4!, ! = −4!   ! = −4+ ! 3,  ! = −4− ! 3  

! = 13!,  ! = −13!  

! = −5+ 4!,  ! = −5− 4!  

! = 3! 3,    ! = −3! 3  

! = 13!,    ! = −13!
