Ayudaaaa por favor doy 30 puntos

Answer 1

Respuesta:

a. P(-5x^3y^2)*Q(7x^5y) = -5x^3y^2*7x^5y = -(5*7)x^3x^5y^2y  = -35x^8y^3

b. P(-5x^3y^2)*S(5x^2-3x+2)= (-5x^3y^2*5x^2)(-5x^3y^2*-3x)(-5x^3y^2+2)

= -(5*5)x^3x^2y^2-(5*-3)x^3xy^2-(5*2)x^3y^2= -25x^5y^2+15x^4y^2-10x^3y^2

c. P(-5x^3y^2)*R(2x^3+3x^2y^2-10xy^3)= (-5x^3y^2*2x^3)(-5x^3y^2*+3x^2y^2)(-5x^3y^2*-10xy^3)= -(5*2)x^3x^3y^2-(5*3)x^3x^2y^2y^2

-(5*-10)x^3xy^3y^2

= -10x^6y^2-15x^5y^4+50x^4y^5.

d.Q(7x^5y)*S(5x^2-3x+2)= (7x^5y*5x^2)(7x^5y*-3x)(7x^5y*+2)

= (7*5)x^5x^2y+(7*-3)x^5xy+(7*2)x^5y = 35x^7y-21x^6y+14x^5y.

e. R(2x^3+3x^2y^2-10xy^3)*S(5x^2-3x+2)= 2x^3(5x^2-3x+2)+3x^2y^2(5x^2-3x+2)-10xy^3(5x^2-3x+2)= 10x^5-6x^4+4x^3+15x^4y^2-9x^3y^2+6x^2y^2-50x^3y^3+30x^2y^3-20xy^3 =

f. Q(7x^5y)*R(2x^3+3x^2y^2-10xy^3)= 7x^5y*(2x^3+3x^2y^2-10xy^3)

=18x^8y+21x^7y^3-70x^6y^4

Espero que te sirva mi respuesta.
