Question

f (x) = x^2+2x-1
g (x)= 2x-1

suma, resta y multiplicación

Answer 1

son operadores matematicos

Answer 2

Suma: [f(x)]+[g(x)] =(x^2+2x-1)+(2x-1) =x^2+2x-1+2x-1 =x^2+4x-2 Resta: [f(x)]-[g(x)] (x^2+2x-1)-(2x-1) =x^2+2x-1-2x+1 =x^2 Multiplicación: [f(x)][g(x)] (x^2+2x-1)(2x-1) =2x^3+4x^2-2x-x^2-2x+1 =2x^3+3x^2-4x+1 Espero que te ayude :)
