To solve the quadratic equation , you can factor it. Look for two numbers that multiply to 15 and add up to 8. These numbers are 3 and 5. Thus, the equation factors to . Setting each factor to zero gives you the solutions and . Easy peasy!

For a different approach, you can use the quadratic formula: . In this case, . Plugging the values into the formula yields the same results: and . This method always works, regardless of whether the quadratic can be factored. Give it a try next time!
