Question

DADOS f(x)= x² +2x + i ; g(x) = - x² -x +3 e h(x)= i x² -2 , obter o polinômio a (x) = f(x) .g(x) + h(x)

​

Answer 1

Resposta:   $-x^{4}-3x^{3}+x^{2}+6x-ix+3i-2$

Olá!

f(x) • g(x) + h(x)

$(x^{2} + 2x + i) * (-x^{2} - x + 3) + (ix^{2} - 2)\\ \\ -x^{4}-x^{3}+3x^{2}-2x^{3}-2x^{2}+6x-ix^{2}-ix+3i~~+ix^{2}-2\\ \\ -x^{4}-3x^{3}+x^{2}+6x-ix+3i-2\\ \\ \\ -x^{3}*(x+3)+x*(x+6)+i(3-x)-2$
