Produtos notaveis a (a+41)² b (w+5)² c (y+10)² d (x+7) (x+7) e (a+3 (a+3) f (y+10) (y+10) g (a+b)²

Answer 1

Explicação passo-a-passo:

a)

(a + 41)² = a² + 2.a.41 + 41²

(a + 41)² = a² + 82a + 1681

b)

(w + 5)² = w² + 2.w.5 + 5²

(w + 5)² = w² + 10w + 25

c)

(y +10)² = y² + 2.y.10 + 10²

(y + 10)² = y² + 20y + 100

d)

(x + 7).(x + 7) = x² + 7x + 7x + 49

(x + 7).(x + 7) = x² + 14x + 49

e)

(a + 3).(a + 3) = a² + 3a + 3a + 9

(a + 3).(a + 3) = a² + 6a + 9

f)

(y + 10).(y + 10) = y² + 10y + 10y + 100

(y + 10).(y + 10) = y² + 20y + 100

g)

(a + b)² = a² + 2.a.b + b²

(a + b)² = a² + 2ab + b²
