Together you can come up with a plan to get you the help you need. See your instructor as soon as you can to discuss your situation. You should get help right away or you will quickly be overwhelmed. …no - I don’t get it! This is a warning sign and you must not ignore it. Is there a place on campus where math tutors are available? Can your study skills be improved? Who can you ask for help? Your fellow classmates and instructor are good resources. It is important to make sure you have a strong foundation before you move on. In math every topic builds upon previous work. This must be addressed quickly because topics you do not master become potholes in your road to success. What did you do to become confident of your ability to do these things? Be specific. Reflect on the study skills you used so that you can continue to use them. ![]() Congratulations! You have achieved the objectives in this section. Ⓐ After completing the exercises, use this checklist to evaluate your mastery of the objectives of this section.Ĭhoose how would you respond to the statement “I can solve quadratic equations of the form a times the square of x minus h equals k using the Square Root Property.” “Confidently,” “with some help,” or “No, I don’t get it.” In your own words, explain how to use the Square Root Property to solve the quadratic equation ( x + 2 ) 2 = 16 ( x + 2 ) 2 = 16. We earlier defined the square root of a number in this way: So, every positive number has two square roots-one positive and one negative. Therefore, both 13 and −13 are square roots of 169. Previously we learned that since 169 is the square of 13, we can also say that 13 is a square root of 169. īut what happens when we have an equation like x 2 = 7? Since 7 is not a perfect square, we cannot solve the equation by factoring. In each case, we would get two solutions, x = 4, x = −4 x = 4, x = −4 and x = 5, x = −5. We can easily use factoring to find the solutions of similar equations, like x 2 = 16 and x 2 = 25, because 16 and 25 are perfect squares. x 2 = 9 x 2 − 9 = 0 ( x − 3 ) ( x + 3 ) = 0 Use the Zero Product Property. x − 3 = 0 x − 3 = 0 x = 3 x = −3 Put the equation in standard form. Let’s review how we used factoring to solve the quadratic equation x 2 = 9. We have already solved some quadratic equations by factoring. Solve Quadratic Equations of the form a x 2 = k a x 2 = k using the Square Root Property In this chapter, we will learn three other methods to use in case a quadratic equation cannot be factored. We have seen that some quadratic equations can be solved by factoring. We use different methods to solve quadratic equations than linear equations, because just adding, subtracting, multiplying, and dividing terms will not isolate the variable. Quadratic equations differ from linear equations by including a quadratic term with the variable raised to the second power of the form ax 2. If you missed this problem, review Example 6.23.Ī quadratic equation is an equation of the form ax 2 + bx + c = 0, where a ≠ 0 a ≠ 0. If you missed this problem, review Example 8.50. If you missed this problem, review Example 8.13. Trending Questions What is the difference between the zero property of multiplication and the identity property of addition?
