(x+4) × (x+4) - 2(x+1)

3x(x-1)+ (x+2) × (x+5)

(m-1)² - (m+1) × (m -1)

(x+4) × (x-4) - (x-4)​

Answer 1

Resposta:

x'2-3x +4x-12+2

x'2-1x-10

x'2+4x +4x+16 -2x -2

x'2-6x-14

Answer 2

Oi....

Resolução:

a)

(x + 4) × (x - 3) + 2

x² - 3x + 4x - 12 + 2

x² + x - 10

b)

(x + 4) × (x + 4) - 2(x + 1)

x² + 8x + 16 - 2x - 2

x² + 6x + 14

c)

3(x - 1) + (x + 2) × (x + 5)

3x - 3 + x² + 5x + 2x + 10

x² + 10x + 7

d)

(m - 1)² - (m + 1) × (m - 1)

(m - 1) × [m - 1 -(m + 1)]

(m - 1) × [m - 1 - m - 1]

(m - 1) × [ - 2]

- 2(m - 1)

e)

(x + 4) × (x - 4) - (x - 4)​

(x - 4) × (x + 4 - 1)

(x - 4)× (x + 3)

Bons estudos.
