Question

subtract the following polynomials
1. (-x^2+x-4)-(3x^2-8x-2)
2.(8x^2-3x)-(5x-5-8x^2)
3.(-x^2-5x-3)-(-7x^2-8x-8)
4.(-2x^3+x)-(7x-3-7x^3)
5.(3x^3+3x^2+9)-(5x^3-7x^2+6x-9)
6.(5x^3+5x^2+5)-(6x^3-6x^2+8x-5)

Answer 1

1)-

-x^2 +x -4 - 3x^2 +8x + 2

=  -4x^2 +9x -2 

2)- 

8x^2 -3x - 5x +5 +8x^2 

= 16x^2 -8x +5 

3)- 

-x^2 - 5x - 3 +7x^2 + 8x + 8

= 6x^2 +3x +5 

4)- 

-2x^3 +x -7x + 3 +7x^3

=  5x^2 -6x +3

5)- 

 3x^3 + 3x^2 + 9 - 5x^3 - 7x^2 + 6x - 9

= -2x^3 - 4x^2 + 6x 

6)- 

5x^3 + 5x^2 + 5 - 6x^3 - 6x^2 + 8x -5

= -x^3 - x^2 + 8x 


i hope this will help you
