Question

hallar : B(x) + 2C(x)





​

Answer 1

Respuesta:

B(x) + 2C(x) = 6x^{3} + 3x^{2} - 6x + 1

Explicación paso a paso:

2C(x)= (x^{3} . 2 ) + (-4x . 2)+ (3 . 2)

2C(x)= 2x^{3} - 8x + 6

B(x) + 2C(x) =  4x^{3}  + 3x^{2} + 2x - 5 + 2x^{3} - 8x + 6

B(x) + 2C(x) = 4x^{3} + 2x^{3} = 6x^{3}

B(x) + 2C(x) = 2x - 8x = -6x

B(x) + 2C(x) =  -5 + 6 = 1

B(x) + 2C(x) = 6x^{3} + 3x^{2} - 6x + 1
