Solve equation by taking square roots
WebSolve Quadratic Equations of the Form ax2 = k Using the Square Root Property. We have already solved some quadratic equations by factoring. Let’s review how we used factoring to solve the quadratic equation x 2 = 9. x 2 = 9 Put the equation in standard form. x 2 − 9 = 0 Factor the left side. ( x − 3) ( x + 3) = 0 Use the Zero Product ... WebAnswer. To begin solving this, we first multiply both sides of the equation 4 𝑥 = 𝑥 9 by 𝑥, which gives 4 = 𝑥 9. . Taking the square root of both sides, considering both the positive and the negative roots, we have ± √ 3 6 = 𝑥 ± 6 = 𝑥. Therefore, 𝑥 = ± 6 and our answer is the set { 6, − 6 }.
