Question

Efetue as multiplicações de polinomios a) (a^ 2 -3).(a^ 2 +3) b) (m ^ 4 - 1) . (m ^ 4 - 5) c) x ^ 2 * (x - 1) d) (x ^ 2 + x + 1) - (x - 3) e) (10+x).(10-x)

Answer 1

Resposta:

a) a⁴-9. d) x³-2x²-2x-3.

b) m⁸-6m⁴+5. e) 100-x².

c) x³-x².

Explicação passo-a-passo:

a) (a²-3).(a²+3)=

(a²)²-(3)²= a⁴-9

b) (m⁴-1).(m⁴-5)=

m⁸-5m⁴-m⁴+5=

m⁸-6m⁴+5

c) x².(x-1)= x³-x²

d) (x²+x+1).(x-3)=

x³-3x²+x²-3x+x-3=

x³-2x²-2x-3

e) (10+x).(10-x)=

(10)²-(x)²= 100-x²
