A student said that (9x)-² = - 81x². This student is not correct.

(9x)^-2 = 1/(9x)^2 = 1/81x^2

(9x)^-2 = 1/(9x)^2 = 1/81x^2

(4x + 1)(x^2 – 9x + 5)

= 4x^3 + x^2 - 36x^2 - 9x + 20x + 5

= 4x^3 - 35x^2 + 11x + 5

= 4x^3 + x^2 - 36x^2 - 9x + 20x + 5

= 4x^3 - 35x^2 + 11x + 5

(4x + 1 )(x2 – 9x + 5) **Weegy:** Best Answer - Chosen by Voters
((4/x) - (2/4x)) / ((1/2x) + (3/2x))
= ((16/4x) - (2/4x))/(4/2x)
= (14/4x)/(2/x)
= (14/4x) * (x/2)
= 14x/8x
= 14/8
= 7/4
