(5x^2 + 3x) + (2x + 5)

= 5x^2 + 2x + 3x + 5

= 5x^2 + 5x + 5

= 5x^2 + 2x + 3x + 5

= 5x^2 + 5x + 5

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
