Question

Efetue conforme o modelo: (x - 8)²= ( 9 - x )²= ( a + 8)²= (5a + 6 )²= (1 - x³) . (1 - x³)=

Answer 1

Explicação passo-a-passo:

(x+8²=x²+8×+9x+81 =x²+18x+81

(8-a)²= 64-8a-8a+a² =64-16a+a²

(x+7).(x-7)= x²-7x+7x-49= x²-49

(x+9).(x+2)= x²+2x+9x+18= x²+11x+18

(x+5).(x+2)= x²+2x+5x+10= x²+7x+10

(x+2).(x²+1)= x³+1x+2x²+2

x³(x-3)= x⁴-3x³

(x-y).(3x²+y)=3x³+xy-3x²y-y²
