Question

x²- 9 = 0 graph please answer this question friends ​

Answer 1

Answer:

x = -3 or x = 3 ( graph)

Step-by-step explanation:

Given,

x² - 9 = 0

= x² - 3² = 0

Using the identity, (a² -b)² = (a + b) (a-b)

(x + 3) ( x - 3) = 0

x + 3 = 0 or x - 3 = 0

x = -3 or x = 3

We can plot the graphs for x = -3 or x = 3.
