Question

Solve the following quadratic equations by completing the square method

(i) 9X²⁻12x+4=0​

Answer 1

Step-by-step explanation:

9x^2-12x +4=0

(3x-..2) 2 =o

3x-2=0

3x=2

x = 2/3

Answer 2

${9x}^{2} - 12x + 4 \\ [ {(3x)}^{2} + 2(3x)( - 2) + {( - 2)}^{2} ] - {( - 2)}^{2} + 4 \\ [ {(3x - 2)}^{2} ] - 4 + 4 \\ {(3x - 2)}^{2}$
