Question

Soma e subtração de polinômios:

F (x) = 4x$x^{5}$-3x$x^{4}$-2x$x^{2}$+8x-3
G (x) = 7x$x^{6}$-3x$x^{5}$+3x$x^{3}$-5x$x^{2}$+7

F(x) + G(x) =?

Answer 1

$f(x) + g(x)\\\\\\\\(4x^{5}-3x^{4}-2x^{2}+8x-3)+(7x^{6}-3x^{5}+3x^{3}-5x^{2}+7)\\\\\\\\7x^{6}+4x^{5}-3x^{5}-3x^{4}+3x^{3}-2x^2}-5x^{2}-3+7\\\\\\\\\ =\ \boxed{\boxed{7x^{6}+x^{5}-3x^{4}+3x^{3}-7x^{2}+4}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ok$
