Answer 1

Answer:

$9x {}^{2} - 12x + 2 = 0 \: solve \: by \: cmpleting \: square \: method$

Step-by-step explanation:

9x^2 - 12x + 2 = 0

9x^2 - 12x = -2

x^2 - 4x/3 = -2 / 9

Third term = (-4/3 × 1/2 )^2

= (-2/3)^2

= 4/9

Add third term to both sides...

x^2 - 4x/3 + 4/9 = -2/9 + 4/9

【 x - 2/3 】 ^2 = 2 / 9

Therefore ....

x - 2/3 = √2 / 3

x = (2 + √2)/3 or x = (2 - √2)/3...
