Question

me ajudem pvr, com a conta pvr ​

Answer 1

Explicação passo-a-passo:

olá,

a) 16x^2 - 64

= 16•(x^4 - 4)

= 16•(x + 2)•(x - 2) <<<

—————

b) 36a^2 - 81b^2

= 9•(4a^2 - 2b^2)

= 9•(2a + 3b)•(2a - 3b) <<<

—————

c) 16x^4 - 1

= 4^2x^4 - 1^2

= 4^2•(x^2)^2 - 1^2

= (4x^2)^2 - 1^2

= (4x^2 + 1) • (4x^2 - 1)

= (4x^2 + 1)•(2x + 1)•(2x - 1) <<<

—————

d) x^8 - 1

= (x^4)^2 - 1^2

= (x^4 + 1)•(x^4 - 1)

= (x^4 + 1)•(x^2 + 1)•(x + 1)•(x - 1) <<<

bons estudos!
