Express in standard form and determine the values of a, b, c

x = 5 + 2x²

write the equation in Standard form :

  • -2x² + x - 5 = 0

determine the values of a, b, c :

  • a = -2
  • b = 1
  • c = -5

Solve the quadratic equation ax² - bx - c = 0 using

  • x = -b ± √b² - 4ac/2a
  • x = -(1) ± √(1)² -4(-2)(-5)/2(-2)
  • x = -1 ± √-39/-4
  • No real solutions
