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 ... 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 ...
