Question

(3/2x+1)^3 - 27/x/4-9x/2 simplify ​

Answer 1

Answer:

1 - 9x

Step-by-step explanation:

³/₂x + 1³ = ⁶/₄x + 1 - ²⁷/ₓ ÷ 4 - ⁹ˣ/₂

1 - 9x

Answer 2

Answer:

1 - 9x

Step-by-step explanation:

(³/₂x + 1)³  - ²⁷/ₓ ÷ 4 - ⁹ˣ/₂

= ⁹/₄x + 1 - ²⁷/ₓ ÷ 4 - ⁹ˣ/₂

=  ⁹/₄x + 1 - ²⁷/ₓ * ¹/₄ -  ⁹/₂x

= ⁹/₄x + 1 - ²⁷/₄x -  ⁹/₂x

= 1 +  ⁹/₄x - ²⁷/₄x -  ⁹/₂x

= 1 + $\frac{9 -27-18}{4} x$

= 1 - $\frac{36}{4} x$

= 1 - 9x
