Question

simplify the following?​

Answer 1

Answer:

a) (2x^2-5x+8)-(x^2+3x-2)+(14-2x)

= 2x^2-5x+8-x^2-3x+2+14-2x

= x^2-10x+24

b) (10x^3-4x^2+3x)-(x^3-x^2+1)-(50x+3)

= 10x^3-4x^2+3x-x^3+x^2-1-50x+3

= 9x^3-3x^2-47x+2

c) (17x-3+7x^2)-(x^3-2x+17)-(3x^3-5x^4-10x+1)

= 17x-3+7x^2-x^3+2x-17-3x^3+5x^4+10x-1

= 5x^4-4x^3+7x^2+29x-21

d) (x^2-6x+5)+(x^2+x-2)-(16-13x)

= x^2-6x+5+x^2+x-2-16+13x

= 2x^2+8x-13
