Storyboard Text

  • Correcting her mistake 
  • -x2+6x-8  A= -1         B= 6      C= -8 
  • Continueing...
  • yeah, now you have to plug in the numbers and solve.
  • Would that be correct?
  • Solving
  • -x2+6x-8  A= -1         B= 6      C= -8                                              -6± (√ (62 ) - 4 (-1)(-8) / 2  (-6 ±  √ 36- 32 ) / 2   
  • Fixing it into standard form can help finally solve the problem.
  • Double Checking to make sure she is correct 
  • No, you would subtract first then find the square root 
  • Now, do I find the square root of  36 or?
  • After correcting her mistake she now has to plug in the numbers for a, b, and c
  • Completing the problem 
  • -x2+6x-8  A= -1         B= 6      C= -8                                              -6± (√ (62 ) - 4 (-1)(-8) / 2  (-6 ±  √ 36- 32 ) / 2    (-6  ±  √ 4) /2  (-6 ± 2) / 2                                             -6 +2 = 4 / 2 = 2  -6-2 = -8 / 2 = -4  
  • yeah. Good job if you need any more help just come and find me. I'll always come and help 
  • Solving the equation and then getting stuck
  • The End
  • Would the final answers be 2 and -4. 
  • Jessica got confused when finding the square roots
  •  Finally completing to solve to get the values of x. In order to complete the problem, she needs to find the square root of the value when she subtracted. Then needs to complete them by adding and or subtracting than dividing. 
  • Ending off by finally understanding doing the quadratic equation.
