Question

a) X² + 7x +10=
b) X² - 13x + 40
c) X² + 9x + 18
d) M² + 11x + 28
fatoração de trinômios

Answer 1

Resposta:

a)

$(x + 5) \times (x + 2)$

b)

$(x - 5) \times (x - 8)$

c)

$(x + 6) \times (x + 3)$

d)

$(x + 7) \times (x + 4)$

Explicação passo-a-passo:

a)

${x}^{2} + 7x + 10 \\ {x}^{2} + 5x + 2x + 10 \\ x \times (x + 5) + 2(x + 5) \\ (x + 5) \times (x + 2)$

b)

${x}^{2} - 13x + 40 \\ {x}^{2} - 5x - 8x + 40 \\ x \times (x - 5) - 8(x - 5) \\ (x - 5) \times (x - 8)$

c)

${x}^{2} + 9x + 18 \\ {x}^{2} + 6x + 3x + 18 \\ x \times (x + 6) + 3(x + 6) \\ (x + 6) \times (x + 3)$

d)

${x}^{2} + 11x + 28 \\ {x}^{2} + 7x + 4x + 28 \\ x \times (x + 7) + 4(x + 7) \\ (x + 7) \times (x + 4)$

ESPERO TER AJUDADO, bjs :)
