SUMMARY

The discussion centers on finding the roots of the exponential equation involving terms 3^x and e^x. It is established that these exponential functions cannot equal zero for real values of x. The only viable equation presented is x^2 - 4 = 0, leading to the definitive roots x = 2 and x = -2. Participants confirm the correctness of this approach, affirming that no additional considerations are necessary.

PREREQUISITES
  • Understanding of exponential functions, specifically 3^x and e^x.
  • Knowledge of quadratic equations, particularly the standard form x^2 - 4.
  • Familiarity with solving equations for real roots.
  • Basic algebraic manipulation skills.
NEXT STEPS
  • Study the properties of exponential functions and their behavior at different values of x.
  • Explore the quadratic formula and its application in solving equations.
  • Investigate the implications of complex roots in polynomial equations.
  • Learn about graphing exponential and quadratic functions to visualize their intersections.
USEFUL FOR

Mathematics students, educators, and anyone interested in solving exponential and quadratic equations will benefit from this discussion.

Homework Statement
Given that f(x)=(3^x).(e^x).(x^2-4) for real x.Find the root of the function.(setting f(x)=0).
Relevant Equations
No equations required.
I know that both 3^x and e^x can't be 0 for real x. Then x^2-4=0 is the only choice and we get x=2,-2. Am I right? Or should I add something?
