Question

Find the roots of the equation below.

x2 - 6x + 9 = 0

-3
3
±3
±3i

Answer 1

The answer is just 3 only because if you plug in 3 to subsitute

Answer 2

Roots of the equation x² - 6x + 9 = 0 are 3,3 .

Explanation:

As given the expression in the question be as follow.

x² - 6x + 9 = 0

Simplify the above equation

x² - 3x - 3x + 9 = 0

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

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

x = 3, 3

Therefore the roots of the equation x² - 6x + 9 = 0 are 3,3 .
