Question

Dado P(x)= 2x2+2x3+3x Q(x) = x3+ 2x2+x. calcule P(x)+Q(x) :

Seleccione una:
a. x3+ x2+x
b. 3x3+ 4x2+x
c. x3+ 4x2+4x
d. 3x3+ 4x2+4x

Answer 1

$p(x) = 2 {x}^{2} + 2 {x}^{3} + 3x \\ q(x) = {x}^{3} + 2 {x}^{2} +x \\ \\ p(x) + q(x) = 2 {x}^{2} + 2 {x}^{3} + 3x + {x}^{3} + 2 {x}^{2} + x \\ p(x) + q(x) = 3 {x}^{3} + 4 {x}^{2} + 4x$
