Answer 1

Step-by-step explanation:

Given :

if 6x² -1= 4x, let's show that 36x² +1/x²= 28. Give me the answer in a few seconds

to find :

Give me the answer in a few seconds

solution :

• 6 x - 1 = 4 x

• 6/x - 1/x = 4/x

• 6 x - 1/x = 4

• squaring both sides

• ( 6/x - 1/x ) = (4)

• 36 x + 1/x - 2 . 6 x 1/x = 16

• 36 x + 1/x - 12 =16

• 36 x + 1/x = 16 + 12 = 28
