Question

Si v(x)=2x^2-3x+2 y w(x)=5x+1 encontrar, A:(v+w)(2) B:(vw)(1)... ayúdenme porfa

Answer 1

Respuesta:

Si v(x)=2x²-3x+2 y w(x)=5x+1

encontrar

(v+w)(x) = 2x²-3x+2 +5x+1

(v+w)(x) = 2x²+2x+3

(v+w)(2) = 2(2)²+2(2)+3

(v+w)(2) = 8 +4+3

(v+w)(2) = 15

encontrar

(vw)(x) = (2x²-3x+2)(5x+1)

(vw)(1) = (2(1)²-3(1)+2)(5(1)+1)

(vw)(1) = (2-3+2)(5+1)

(vw)(1) = (1)(6)

(vw)(1) = 6
