Solving equations by taking square roots
WebJul 24, 2024 · Solve Quadratic Equations of the Form ax 2 = 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 x2 = 9. x2 = 9 Put the equation in standard form. x2 − 9 = 0 Factor the left side. (x − 3)(x + 3) = 0 Use the Zero Product Property ... WebUse 5 and 1. (x+5) (x+1) = 0. -- Use the zero product rule. Split the factors and set each individually = 0 and solve. x + 5 = 0 creates x = -5. x + 1 = 0 creates x = -1. You will later …

WebSo the actual answer to the above question is: x = + 7 and − 7. or. x = ± 7. (this is said “plus or minus seven”) In fact, every time you solve an equation using a square root (unless x=0) you will have TWO answers, a positive and a negative number. Let’s try a tougher one: 8 x 2 − 8 = 328. We cannot take the square root until x 2 is ... WebThe inverse operation of taking the square is taking the square root. However, unlike the other operations, when we take the square root we must remember to take both the positive and the negative square roots. Now solve a few similar equations on your own.

WebSolving Quadratic Equations Using Square Roots. The general form of a quadratic equation is: a x 2 + b x + c = 0. If b = 0 , the equation can solved by putting it in the form. x 2 = d. for … 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 }.
