Quadratic Equations and Their Solutions

The video tutorial demonstrates solving a quadratic equation using both the quadratic formula and factoring. Initially, the equation is set up in the standard form, and the quadratic formula is applied to find the solutions. The process involves substitution and simplification, revealing that the solutions are real and rational. The tutorial then verifies these solutions by factoring the equation, confirming the results. The video concludes by emphasizing the versatility of the quadratic formula in solving various types of quadratic equations.

What is the quadratic equation given in the example?

• 36x^2 + 49 = 0

• 49x^2 - 36 = 0

• 36x^2 - 49 = 0
