[tex]P(x) = 5x+6 \ \ \ \ \ g(x) =4x^{3} -8x^{2}+6x-10 \\\\ Hallar: P (x)+g(x) \ \ \ \ P(x)-g(x) \ \ \ \ \ P(x).g(x) \\\\ P(x)+g(x)=\\\\ 5x+6+4x^{3}-8x^{2}+6x-10= 4x^{3} -8x^{2}+11x-4 \\\\ P(x)-g(x)= \\\\ 5x+6-(4x^{3}-8x^{2}+6x-10)= \\\\ 5x+6 - 4x^{3}+8x^{2}-6x+10= \\\\ - 4x^{3}+8x^{2}-x+16 \\\\ P(x).g(x)= \\\\ (5x+6)(4x^{3}-8x^{2}+6x-10)= \\\\ 20x^{4}-40x^{3}+30x^{2}-50x+24x^{3}-48x^{2}+36x-60= \\\\ 20x^{4}-16x^{3}-18x^{2}-14x-60 \\\\ espero \ \ haberte \ \ ayudado[/tex]
