Question

What is the solution of 4x^2-12x + 9 = 0​

Answer 1

x =
`(3)/(2)`

Explanation:

4x² - 12x + 9 = 0 ← the quadratic is a perfect square

(2x - 3)² = 0 , then

2x - 3 = 0 ( add 3 to both sides )

2x = 3 ( divide both sides by 2 )

x =
`(3)/(2)` ( repeated root )

Answer 2

Answer is: (2x-3)(2x-3) or (2x-3)^2
