Question

4.Efetue As multiplicações dos polinômios.
d)(x+1/2)(x^2+x+1/4)
g)(a^2-b)(a^2b+4ab^2+2b^3)

Answer 1

Resposta:

d)

$(x+\frac{1}{2} )(x^{2}+x+\frac{1}{4} )=>x^{3}+x^{2}+\frac{x}{4}+ \frac{x^{2} }{2} +\frac{x}{2} +\frac{1}{8}=>x^{3}+\frac{3x^{2} }{2} +\frac{3x}{4}+\frac{1}{8}$

g)

$(a^{2}-b)(a^{2}b+4ab^{2}+2b^{3}) =>a^{4}b+4a^{3}b^{2}+2a^{2}b^{3} -a^{2}b^{2} -4ab^{3}-2b^{4}$
