Question

resolva as operações envolvendo polinomios:
a) 3a² -5a +9a +2a² -8 +3a²

b) (5x² -2x +3) - (3x² -7x +5)

c) ( -16a³ b²) : ( 8a³b)

d) ( -6ax) · ( -5a³x)

Answer 1

$3 a^{2} -5a+9a+2 a^{2}-8+3 a^{2} \\ (3 a^{2}+2 a^{2}+3 a^{2})+( 5a+9a)-8 \\ \boxed{\boxed{8a^{2}-4a-8}}$

$( 5x^{2} -2x+3)-(3 x^{2}-7x+5) \\\boxed{\boxed{ 2 x^{2} +5x-2 }}$

$\frac{-16ax^{3}+b ^{2} }{ 8a^{2+b} } \\ \boxed{\boxed{-2}}$

$-6ax.(5 a^{3}x) \\ \boxed{\boxed{30 a^{4} x^{2} }}$
