Question

Desenvolva os binômios abaixo: URGENTE
a) (x + 2) ² =
b) (a + 3) ² =
c) (x + 3) ² =
d) (a + 4) ² =
e) (x + 5) ² =

Answer 1

Explicação passo-a-passo:

a)

(x + 2)² = x² + 2.x.2 + 2²

(x + 2)² = x² + 4x + 4

b)

(a + 3)² = a² + 2.a.3 + 3²

(a + 3)² = a² + 6a + 9

c)

(x + 3)² = x² + 2.x.3 + 3²

(x + 3)² = x² + 6x + 9

d)

(a + 4)² = a² + 2.a.4 + 4²

(a + 4)² = a² + 8a + 16

e)

(x + 5)² = x² + 2.x.5 + 5²

(x + 5)² = x² + 10x + 25

Answer 2

Oie, Td Bom?!

a)

$= (x + 2) {}^{2}$

$= x {}^{2} + 2x \: . \: 2 + 2 {}^{2}$

$= x {}^{2} + 4x + 4$

b)

$= (a + 3) {}^{2}$

$= a {}^{2} + 2a \: . \: 3 + 3 {}^{2}$

$= a {}^{2} + 6x + 9$

c)

$= (x + 3) {}^{2}$

$= x {}^{2} + 2x \: . \: 3 + 3 {}^{2}$

$= x {}^{2} + 6x + 9$

d)

$= (a + 4) {}^{2}$

$= a {}^{2} + 2a \: . \: 4 + 4 {}^{2}$

$= a {}^{2} + 8a + 16$

e)

$= (x + 5) {}^{2}$

$= x {}^{2} + 2x \: . \: 5 + 5 {}^{2}$

$=x {}^{2} + 10x + 25$
