Question

polinomios
A-(x^2 - 3x +5) +(x^2+5x-1)=
B-(x^2+2x-4) + (x^2+5x-1)=

Answer 1

a) x^2-3x+5+x^2+5x-1
x^2+x^2-3x+5x+5-1
2x^2+2x+4

b) x^2+2x-4+x^2+5x-1
x^2+x^2+2x+5x-4-1
2x^2+7x-5

Answer 2

a)
= x² - 3x + 5 + x² + 5x - 1
= x² + x² - 3x + 5x + 5 - 1
= 2x² + 2x + 4

***************************************
b)
= x² + 2x - 4 + x² + 5x - 1
= x² + x² + 2x + 5x - 4 - 1
= 2x² + 7x - 5
