9 Subtract the following polynomials: *
(1 Point)
(4x2 - 17x3 + 9) - (x² + 9x + 23x² + 11)
0 - 19.73 – 25x2 – 12x – 3
- 10.x3 – 162x2 – 24x - 4
-17x3 - 20x2 – 9x 2
-16x3 – 243x2 – 12x – 3

Step-by-step explanation:

1) Your problem → (4x^2 - 17x^3 + 9) - (x^2 + 9x + 23x^2 + 11)

(-17x^3+4x^2+9)-(x^2+23x^2+9x+11)

=-17x^3+4x^2+9-x^2-23x^2-9x-11

=-17x^3+4x^2-x^2-23x^2-9x+9-11

=-17x^3-20x^2-9x-2

2) Your problem → 0 - 19.73 - 25x^2 - 12x - 3

=0-19.73-25x2-12x-3

=-25x^2-12x-22.73

3) - 10.x^3 – 162x^2 – 24x - 4

4) Your problem → 17x^3 - 20x^2 - 9x^2

=17x^3-20x^2-9x^2

=17x^3-29x^2

5) -16x^3 – 243x^2 – 12x – 3

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
