Part 4 of using the quadratic formula to solve quadratic equations in standard form.
  • How do you use the quadratic formula to solve quadratic equations?
  • How do you use the quadratic formula to solve 7x(x - 2) + 2(x + 4) = 3?
  • How do you solve 7x(x - 2) + 2(x + 4) = 3 by factoring?
  • When is it faster to solve a quadratic equation by factoring rather than using the quadratic formula?
  • How do you check your solution to a quadratic equation?
This lesson shows how to solve a quadratic equation that first needs to be simplified using the quadratic formula and also by factoring. Both methods are explained with all work shown. You will also learn how to check your solution.
