Question

Solve this question middle term​

Answer 1

Answer:

-x/3 +3/x = x/12 + 12/x

= -x²+9/3x = x²+144/12x

= 12x(-x²+9) = 3x(x²+144)

= -12x³+108x = 3x³+432x

= -12x³-3x³ = 432x-108x

= -15x³ = 324x

= -15x² = 324

= x² = 324/15

= x = √324/15

Answer 2

Answer:

x = 6

Step-by-step explanation:

x / 3 + 3 / x = x / 12 + 12 / x

= (x²+9) / 3x = (x²+144) / 12x

= (x²+9) = (x²+144) / 4

= 4x² + 36 = x²+144

= 4x²-x² = 144-36

= 3x² = 108

= x² = 108 / 3

= x² = 36

= x = √36

= x = 6 ans.
