Question

The solution of any equation is the value of the variable that makes the equation true. The equation x + 3 = 5 has the solution x = 2 because 2 + 3 = 5. Find the solutions to the following questions by finding the value of each of their variables. Part A In question 1, you found the squares of both positive and negative numbers. From the values you entered in the tables, what value or values can you substitute for x in x2 = 9 to make the equation true?

Answer 1

Answer:

Step-by-step explanation:

There are both positive and negative values to substitute for x in x2 = 9. In the positive numbers, 32 = 9, so x = 3 is a solution. In the negative numbers, -32 = 9, so x = -3 is also a solution. The solutions for x2 = 9 are 3 and -3.

Answer 2

Answer:

There are both positive and negative values to substitute for x in x2 = 9. In the positive numbers, 32 = 9, so x = 3 is a solution. In the negative numbers, -32 = 9, so x = -3 is also a solution. The solutions for x2 = 9 are 3 and -3.
