Composition of linear and quadratic functions: find a valueright chevron icon

Full solution

Q. X2+6−8=0X^2+6-8=0
  1. Combine like terms: Simplify the equation by combining like terms.\newlineX2−2=0X^2 - 2 = 0
  2. Isolate X^22: Solve for XX by isolating X2X^2.\newlineAdd 22 to both sides:\newlineX2=2X^2 = 2
  3. Take square root: Take the square root of both sides to solve for XX.\newlineX=±2X = \pm \sqrt{2}
