Question

determine o valor dos polinômios:
5×.(3×2+8)


7×.(xy+7×-9y)


(4z2+5).(4z2+5)


(y+8).(y+8)


(a-6).(a+6)


(2×-3).(2x-3)

​

Answer 1

Explicação passo a passo:

5×.(3×2+8)

15x²+40

7×.(xy+7×-9y)

7x²y+49x²-54xy

(4z²+5).(4z²+5)

16z⁴+20z²+ 20z²+20

16⁴+40z²+20

(y+8).(y+8)

y²+8y+8y+64

2y²+16Y+64

(a-6).(a+6)

a²+6a -6a-36

a²-36

(2×-3).(2x-3)

4x²-6x-6x+9

4x²-12x+9
