Question

Qual o resultado
(3z+ y+1/2).(1+y+2y+5z)
Me ajudem pfv essa questão vale nota

Answer 1

$(3z+y+ \frac{1}{2}).(1+y+2y+5z)=\\3z+3yz+6yz+15 z^{2} +y+ y^{2} +2 y^{2} +5yz+ \frac{1}{2}+ \frac{y}{2}+ \frac{2y}{2}+ \frac{5z}{2}=\\ 3z+ \frac{5z}{2}+3yz+6yz+5yz+15 z^{2} +y+ \frac{y}{2} + \frac{2y}{2}+ y^{2} +2 y^{2} + \frac{1}{2} \\ \frac{6z+5z}{2}+14yz+15 z^{2} + \frac{2y+y+2y}{2}+3 y^{2}+ \frac{1}{2}=\\ \frac{11z}{2}+14yz+15z^{2} + \frac{5y}{3}+3 y^{2} + \frac{1}{2}$
