Answer 1

Resposta:

a)a² + 10.a + 25

b)x² + 6x + 9

c)y² + 20y + 100

d)x² + 14x + 49

e)a² + 8a + 16

f)x² + 2x + 1

g)4x² + 4xy + y²

h)9a² + 24a + 16

i)25+ 30x + 9x²

j)x^ + 2.x.a? + um⁴

Explicação passo-a-passo:

a) (a + 5)² = a² + 2.a.5 + 5²

=a² + 10.a + 25

--------------------------------------

b) (x + 3)² = x² + 2.x.3 + 3²

(x + 3)² = x² + 2.x.3 + 3²= x² + 6x + 9

--------------------------------------

c) (y + 10)² = y². +2.a.10 + 10²

(y + 10)² = y². +2.a.10 + 10²= y² + 20y + 100

--------------------------------------

d) (x + 7)(x + 7) = (x + 7)² = x² + 2.x.7 + 7²

(x + 7)(x + 7) = (x + 7)² = x² + 2.x.7 + 7²= x² + 14x + 49

--------------------------------------

e)(a + 4)(a + 4) = (a + 4)² = a² + 2.a.4 +4²

(a + 4)(a + 4) = (a + 4)² = a² + 2.a.4 +4²= a² + 8a + 16

--------------------------------------

f)(x + 1)(x + 1) = (x + 1)² = x² + 2.x.1 + 1²

(x + 1)(x + 1) = (x + 1)² = x² + 2.x.1 + 1²= x² + 2x + 1

--------------------------------------

g) (2x + y)² = (2x)² + 2,2x.y + y²

=4x² + 4xy + y²

--------------------------------------

h) (3a + 4)² = (3a)² + 2.3a.4 +4²

(3a + 4)² = (3a)² + 2.3a.4 +4²= 9a² + 24a + 16

--------------------------------------

i) (5 + 3x)² = 5² + 2,5,3x + (3x)²

(5 + 3x)² = 5² + 2,5,3x + (3x)²= 25+ 30x + 9x²

--------------------------------------

j)(x² + a²)² = (x²)² + 2.x².a² + (a²)²

= x^ + 2.x.a? + um⁴
