Question

what are tha root of quadratic equation x square =9​

Answer 1

Answer:

One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored: (x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = -3 or 3

Answer 2

${x}^{2} = 9 \\ x = 3 \: or \: ( - 3)$
