Produtos Notáveis:

a) (5-y)²=

b) (m-6)²=

c) (2x-3)²=

d) (1+m)²=

e) (3x+1)²=

Answer 1

a) (5-y)²= 5² - 2.5.y + y² = 25 - 10y + y² = y² - 10y + 25

b) (m-6)²= m² - 2.6m + 6² = m² - 12m + 36
 
c) (2x-3)²= (2x)² - 2.3.2x + 3² = 4x² - 12x + 9

d) (1+m)²= 1² + 2.1.m + m² = 1 + 2m + m² = m² + 2m + 1

e) (3x+1)²= (3x)² + 2.1.3x + 1² = 9x² + 6x + 1
