  • Hello! Today I will be learning how to use the quadratic formula.
  • The Equation:-b+-√b^2-4ac-----------------2a
  • Our Equation: 2x^2+2x-5=0 In Quadratic Form: -2+-√(2)^2-4(2)(-5) -------------------2(2)
  • Starting to solve:-2+-√4+40---------------4
  • Add it!-2+-√44------------4
  • Square Root:*Since this doesn't square nicely we have to use the jailbreak method:-2+-2√11--------------4
  • We have to get rid of the 2:-2/2+-2√11/2-------------4/2
  • Final Answer:-1+-√11------------2
  • Thanks for learning with me!
