Question

slove the equation x²+1/6x - 2 by completing the square method​

Answer 1

Answer:

x²+1(6x-2) = 6x⅜ √π2²✓✓

Answer 2

Answer:

Step-by-step explanation:

x² + 1x/6 - 2 = 0

⇒ x² + 1x/6 = 2

⇒x² + 1x/6×2 = 2 + 1/6×2

⇒x² + (1x/12)² = 2 + (1/12)²

 (x + 1/12² )= 2 +1/144

 (x + 1/12)² =  (288 + 1)/144

 (x + 1/12) = $\sqrt{289}$/144

 x = - 1/12 ± $\sqrt{289}$ /144

 x = -1/12 ± 17 /12

 x = -1/12 + 17/12    or    x = -1/12 - 17/12

 ⇒ x = 16/12       or     x = -18/12

 ⇒ x = 4/3     or    x = 3/2
