Question

me ajudemm , façam os cálculos pfvv
A)(x+2)²=
B)(x+9)²=
C)(x+8)²=
D(y+10)²=
E(x+11)²=
F(6+y)²=

Answer 1

Oi...

a)

(x + 2)²

(x + 2)(x + 2)

x² + 2x + 2x + 4

x² + 4x + 4

b)

(x + 9)²

(x + 9)(x + 9)

x² + 9x + 9x + 81

x² + 18x + 81

c)

(x + 8)²

(x + 8)(x + 8)

x² + 8x +  8x + 64

x² + 16x + 64

d)

(y + 10)²

(y + 10)(y + 10)

y² + 10y + 10y + 100

y² + 20y + 100

e)

(x + 11)²

(x + 11)(x + 11)

x² + 11x + 11x + 121

x² + 22x + 121

f)

(6 + y)²

(6 + y)(6 + y)

36 + 6y + 6y + y²

y² + 12y + 36

Espero ter ajudado.
