Question

Alguna persona que sea tan amable de ayudarme a resolver?

Answer 1

Suma y resta de los polinomios:

• (10x+9x^2-5) y (6x^2+3-7x):

Suma = (10x+9x^2-5) + (6x^2+3-7x) = 15x^2+3x-2

Resta= (10x+9x^2-5) - (6x^2+3-7x) = 3x^2+17x-8

• (10x^4+2x^3-5x^2+10x-3) y (6x^4+3x^3+9x^2+7x+4)

Suma = (10x^4+2x^3-5x^2+10x-3) +  (6x^4+3x^3+9x^2+7x+4)

Suma = 16x^4+5x^34+x^2+17x+1

Resta = (10x^4+2x^3-5x^2+10x-3) - (6x^4+3x^3+9x^2+7x+4)

Resta = 4x^4-x^3-14z^2+3x-7

• (6x^4-5x^2+10x) y (3x^3+9x^2+4)

Suma = (6x^4-5x^2+10x) + (3x^3+9x^2+4) = 6x^4+3x^3+4x^4+10x+4

Resta = (6x^4-5x^2+10x) - (3x^3+9x^2+4) = 6x^4-3x^3-14x^2+10x-4

• (1/3x^4-4x+1) y (2/3x^4+3x^3+100)

Suma = (1/3x^4-4x+1) +  (2/3x^4+3x^3+100) = x^4+3x^3-4x+101

Resta = (1/3x^4-4x+1) - (2/3x^4+3x^3+100) = -1/3x^4-3x^3-4x-99
