Question

What are the roots of the quadratic equation x² = 9?​

Answer 1

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

Step-by-step explanation:

x2 = 9 is to subtract 9 from both sides to

get one side equal to O: 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.
