Question

if (2x+1/2x)=17/4 then value of 8x+1/8x​

Answer 1

Answer:

(17±15)÷2 + 2 ÷ (17±15)

Step-by-step explanation:

(2x+1/2x)=17/4

4x² + 1 = 17/2 x

4x² - 17/2 x +1 = 0

x² - 17/8 x +1/4 = 0

x = 17/8 ± √ (17/8)² - 1 ÷2

x = 17/8 ±  (15/8) ÷2

x = (17±15)÷16

8x = (17±15)÷2

1/8x = 2 ÷ (17±15)

8x+1/8x = (17±15)÷2 + 2 ÷ (17±15)
