Associe as colunas: ( I ) (x +7)2 ( ) (X -7).(X+7) ( II ) (x-7)2 ( ) x2 - 7x + 6 ( III ) x2 -49 ( ) x2 + 14x + 49 ( IV ) (x+1).(x+6) ( ) x2 - 14x + 49 ( V ) (x-1).(x -6) ( ) x2 + 7x + 6

Answer 1

Explicação passo-a-passo:

• I) (x + 7)² = x² + 14x + 49

• II) (x - 7)² = x² - 14x + 49

• III) x² - 49 = (x - 7)(x + 7)

• IV) (x + 1)(x + 6) = x² + 7x + 6

• V) (x - 1)(x - 6) = x² - 7x + 6

( III ) (x - 7)(x + 7)

( V ) x² - 7x + 6

( I ) x² + 14x + 49

( II ) x² - 14x + 49

( IV ) x² + 7x + 6
