Question:-

What is the solution set for the quadratic equation x² - 9 = 0 ?

Solution:-

x² - 9 = 0 ( Given quadratic equation )

x² = 9

x = ± [tex] \sqrt 9 [/tex]

x = ± 3

The solution set for the quadratic equation x² - 9 = 0 is +3 or -3 [Answer]

Answer:

x = ± 3

Step-by-step explanation:

Given

x² - 9 = 0 ( add 9 to both sides )

x² = 9 ( take the square root of both sides )

x = ± [tex]\sqrt{9}[/tex] = ± 3

That is x = - 3 or x = 3
